Shaykh Abdur-Rahman ibn as-Sa’di :
The Light of the heavens and the earth, the One Who illuminates the hearts of the gnostics with knowledge of Him, faith in Him and His guidance. He is the One Who has lighted the heavens and the earth with lights that He has placed therein. His veil is light and were He to uncover it then the Face of the Glorious would burn everything from the creation that His Sight fell upon.
“Allah is the Light of the heavens and the earth. The parable of His Light is as if there were a niche and within it a lamp, the lamp is in a glass, and the glass as if it were a brilliant star, lit from a blessed tree, an olive, neither of the east or of the west, whose oil would almost glow forth (of itself) even though no fire touches it. Light upon light! Allah guides to His Light whom He Wills. Allah sets forth parables for mankind, and Allah Knows everything.” (24:35)
Dr. Saleh As-Saleh (rahimahullaah):
“Those who negate Allaah’s Attribute of An-Nur erred by thinking that if they would affirm the Attribute of An-Nur, it would mean that Allaah is the light falling upon walls and gardens, etc.! The fact however is that the created light is an effect of the Attribute of An-Nur. We know that Ar-Rahmah (Mercy) is an Attribute of Allaah established with Him. The rahmah (mercy) present on earth is an effect of Allaah’s Attribute of Ar-Rahmah separted from Him. The knowledge of the creature is a distinct and separate effect of Allaah’s Attribute of Knowledge. The saying of ‘Abdullaah ibn Mas’oud does not mean or imply that the light on walls and on the surface of the earth is the essence of the Light of Allaah’s most honourable Face.”

Noorus-Samaawaati Wal-Ardh (Light of the Heavens and the Earth)
“Allah is the Light of the Heavens and the Earth. the parable of His light is as if therewere a niche and within it a lamp; the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east nor of the west, whose oil would almost glow forth of itself, though no fire touched it. Light upon Light! Allah guides to His Light whom He wills. And Allah sets forth parables for mankind, and Allah is All-Knower of everything.” [An-Noor 24:35]
The Prophet Muhammad sallallahu ‘alaihi wa sallam (sallallahu ‘alaihi wa sallam) said:
Oh Allah for You is the praise and You are the Light of the Heavens and the Earth and all therein… [Al-Bukhaari and Muslim]
This is a great Attribute since it describes the One Possessing Majesty and Honor and deserving of glorification and praise and Who if He were to remove the veil from His Noble Countenance all that would be exposed to it in the creation would be disintegrated and His Light would illuminate all the creation and it is the Light from his Countenance that brings light to all darkness and that lights up the Arsh, the Kursi and the seven levels of heaven, indeed all the universe.
His Light is of two types:
1. That which is perceived (hissee) such as the light that emanates from the universe and that would not exist without His light.
2. The spiritual (ma’nawee) which reaches the hearts and the hearing and the vision and that constitutes the light for the slaves in this life and the next.
“Allah guides with His Light whom He wills”. And just as Allah has mentioned, He is the Light of the Heavens and the Earth, He has also called His Book and His Messenger and the Revelation light. – As-Sadee
What must be avoided are the excesses of the Sufis who went too far and did not distinguish between Light as a description of the self and the light of faith and knowledge. Due to worshipping and deifying without complete knowledge some among them perceived the light that comes to the heart from the sincere worship of Allah meant that the person themselves became a part of Allah or had a part of Allah the Most Holy in them so much incorrect and ugly speech emanated from them due to delusion and ignorance in this regard and Allah is Most High and free from what they wrongly attributed to Him.
The people of knowledge however distinguished between the Light that is a part of Allah and His Attribute and the light given to the creation both perceived and spiritual. The believer who perfects his faith is given light in his heart from Allah so that he sees the reality of things and he can clearly distinguish between falsehood and truth until it becomes a part of his life and his power toward good in knowledge and action. He is cleared of doubts and confusion and gets knowledge and clarity and is freed from lusts and negligence and darkness. His speech and actions are characterized as light and he is surrounded by it, while the disbeliever or the hypocrite, the rebellious and unmindful wander about confused and in darkness and all this is due to what they have themselves done .
The Parable of the Light of Allah
[The following is from Tafsir Ibn Kathir]
`Ali bin Abi Talhah reported that Ibn `Abbas said:
(Allah is the Light of the heavens and the earth.) means, the Guide of the inhabitants of the heavens and the earth. Ibn Jurayj said: “Mujahid and Ibn `Abbas said concerning the Ayah:
(Allah is the Light of the heavens and the earth.) He is controlling their affairs and their stars and sun and moon.” As-Suddi said concerning the Ayah:
(Allah is the Light of the heavens and the earth.) by His Light the heavens and earth are illuminated. In the Two Sahihs, it is recorded that Ibn `Abbas, may Allah be pleased with him, said: “When the Messenger of Allah got up to pray at night, he would say:
(O Allah, to You be praise, You are the Sustainer of heaven and earth and whoever is in them. To You be praise, You are the Light of the heavens and the earth and whoever is in them. ) It was narrated that Ibn Mas`ud said, “There is no night or day with your Lord; the Light of the Throne comes from the Light of His Face.”
(The parable of His Light) There are two views concerning the meaning of the pronoun (His). The first is that it refers to Allah, may He be glorified and exalted, meaning that the parable of His guidance in the heart of the believer is
(as a niche) This was the view of Ibn `Abbas. The second view is that the pronoun refers to the believer, which is indicated by the context of the words and implies that the parable of the light in the heart of the believer is as a niche. So the heart of the believer and what he is naturally inclined to of guidance and what he learns of the Qur’an which is in accordance with his natural inclinations are, as Allah says:
(Can they who rely on a clear proof from their Lord, and whom a witness from Him recites it (can they be equal with the disbelievers)) [11:17]. The heart of the believer in its purity and clarity is likened to a lamp in transparent and jewel-like glass, and the Qur’an and Shari`ah by which it is guided are likened to good, pure, shining oil in which there is no impurity or deviation.
(as (if there were) a niche) Ibn `Abbas, Mujahid, Muhammad bin Ka`b and others said, “This refers to the position of the wick in the lamp.” This is well-known, and hence Allah then says:
(and within it a lamp.) This is the flame that burns brightly. Or it was said that the niche is a niche in the house. This is the parable given by Allah of obedience towards Him. Allah calls obedience to Him as light, then He calls it by other numerous names as well. Ubayy bin Ka`b said, “The lamp is the light, and this refers to the Qur’an and the faith that is in his heart.” As-Suddi said, “It is the lamp.”
(the lamp is in a glass,) means, this light is shining in a clear glass. Ubayy bin Ka`b and others said, “This is the likeness of the heart of the believer.”
(the glass as it were a star Durriyyun,) Some authorities recite the word Durriyyun with a Dammah on the Dal and without a Hamzah, which means pearls, i.e., as if it were a star made of pearls (Durr). Others recite it as Dirri’un or Durri’un, with a Kasrah on the Dal, or Dammah on the Dal, and with a Hamzah at the end, which means reflection (Dir’), because if something is shone on the star it becomes brighter than at any other time. The Arabs call the stars they do not know Darari. Ubayy bin Ka`b said: a shining star. Qatadah said: “Huge, bright and clear.”
(lit from a blessed tree,) means, it is derived from olive oil, from a blessed tree.
(an olive,) This refers to the blessed tree mentioned previously.
(neither of the east nor of the west,) means, it is not in the eastern part of the land so that it does not get any sun in the first part of the day, nor is it in the western part of the land so that it is shaded from the sun before sunset, but it is in a central position where it gets sun from the beginning of the day until the end, so its oil is good and pure and shining. Ibn Abi Hatim recorded that Ibn `Abbas commented on:
(an olive, neither of the east nor of the west,) “This is a tree in the desert which is not shaded by any other tree or mountain or cave, nothing covers it, and this is best for its oil.” Mujahid commented on:
(neither of the east nor of the west, ) saying; “It is not in the east where it will get no sun when the sun sets, nor is it in the west where it will get no sun when the sun rises, but it is in a position where it will get sun both at sunrise and sunset.” Sa`id bin Jubayr commented:
(an olive, neither of the east nor of the west, whose oil would almost glow forth (of itself)) “This is the best kind of oil. When the sun rises it reaches the tree from the east and when it sets it reaches it from the west, so the sun reaches it morning and evening, so it is not counted as being in the east or in the west.”
(whose oil would almost glow forth (of itself), though no fire touched it.) `Abdur-Rahman bin Zayd bin Aslam said (this means) because the oil itself is shining.
(Light upon Light!) Al-`Awfi narrated from Ibn `Abbas that this meant the faith and deeds of a person. As-Suddi said:
(Light upon Light!) “Light of the fire and the light of the oil: when they are combined they give light, and neither of them can give light without the other. Similarly the light of the Qur’an and the light of faith give light when they are combined, and neither can do so without the other.”
(Allah guides to His Light whom He wills.) means, Allah shows the way to the ones whom He chooses, as it says in the Hadith recorded by Imam Ahmad from `Abdullah bin `Amr, who said, “I heard the Messenger of Allah say:
(Allah created His creation in darkness, then on the same day He sent His Light upon them. Whoever was touched by His Light on that day will be guided and whoever was missed will be led astray. Hence I say: the pens have dried in accordance with the knowledge of Allah, may He be glorified.)”
(And Allah sets forth parables for mankind, and Allah is All-Knower of everything.) Having mentioned this parable of the Light of His guidance in the heart of the believer, Allah ends this Ayah with the words:
(And Allah sets forth parables for mankind, and Allah is All-Knower of everything.) meaning, He knows best who deserves to be guided and who deserves to be led astray. Imam Ahmad recorded that Abu Sa`id Al-Khudri said, “The Messenger of Allah said:
(Hearts are of four kinds: the heart that is clear like a shining lamp; the heart that is covered and tied up; the heart that is upside-down; and the heart that is clad in armor. As for the clear heart, it is the heart of the believer in which is a lamp filled with light; as for the covered heart, this is the heart of the disbeliever; as for the upside-down heart, this is the heart of the hypocrite, who recognizes then denies; as for the armor-clad heart, this is the heart in which there is both faith and hypocrisy. The parable of the faith in it is that of legume, a sprout that is irrigated with good water, and the likeness of the hypocrisy in it is that of sores that are fed by blood and pus. Whichever of the two prevails is the characteristic that will dominate.) Its chain of narrators is good (Jayyid) although they (Al-Bukhari and Muslim) did not record it.
