Imam Al-Nawawi’s Riyad-us-Saliheen
Uprightness and Steadfastness
Allah, the Exalted, says:
“So stand (ask Allah to make) you (Muhammad (sallallaahu alayhi wa sallam)) firm and straight (on the religion of Islamic Monotheism) as you are commanded…” (11:112)
“Verily, those who say: `Our Rubb is Allah (Alone),’ and then they stand firm, on them the angels will descend (at the time of their death) (saying): ‘Fear not, nor grieve! But receive the glad tidings of Jannah which you have been promised! We have been your friends in the life of this world and are (so) in the Hereafter. Therein you shall have (all) that your inner-selves desire, and therein you shall have (all) for which you ask. An entertainment from (Allah), the Oft-Forgiving, Most Merciful.”’ (41:30-32)
“Verily, those who say: `Our Rubb is (only) Allah,’ and thereafter stand firm and straight (on the Islamic Faith of Monotheism), on them shall be no fear, nor shall they grieve. Such shall be the dwellers of Jannah, abiding therein (forever), – a reward for what they used to do.” (46:13,14)
85. Sufyan bin `Abdullah (May Allah be pleased with him) reported: I said, “O Messenger of Allah, tell me something of Islam which I will not ask anyone else about it.” He (sallallaahu alayhi wa sallam) said, “Say, `I believe in Allah’ and then be steadfast”.
86. Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (sallallaahu alayhi wa sallam) said, “Follow the Right Path of Faith strictly, and be steadfast; and keep in mind that none of you can achieve salvation through his (good) actions.” Someone asked, “Not even you, O Messenger of Allah?” He (sallallaahu alayhi wa sallam) said, “Not even me, unless Allah grants me His Mercy and Grace”.
