On the authority of 'Abdullaah bin 'Umar radiAllaahu anhu, who said : The Messenger of Allaah (sallAllaahu alayhi wa sallam) took me by the shoulder and said :
And Ibn 'Umar (radiAllaahu anhu) used to say :
It was related by al-Bukhaaree.
And al-'Izz 'Alaa-ud-Deen bin Yahyaa bin Hubairah (rahimahu Allaah) said : In this hadeeth is evidence that the Messenger of Allaah sallAllaahu alayhi wa sallam encouraged emulation of the strangers, since when a stranger enters a foreign land he does not compete with its people to attend their gatherings, nor does he worry about being seen in a state and condition opposite to that which is his normal habit in terms of his dress, nor does he try to behave contrary to the customs of the local people. And similarly is the condition of the traveller who does not take a permanent abode of residence, nor does he enter into arguments with the local people which might cause hatred between them, knowing that he will only be amongst them for a few days. So all the conditions of the stranger and the traveller are beloved for the Believer in this dunyaa, as the dunyaa is not his true abode of residence. Rather, the dunyaa is merely an obstruction that prevents him from reaching his true abode and dwelling place in the Hereafter.
And as for the statement of Ibn 'Umar (radiAllaahu anhu) : "In the evening do not expect [to live until] the morning, and in the morning do not expect [to live until] the evening", then this is an encouragement from him for the Believers to always be prepared for the eventuality of death. And death is prepared for with Good Deeds. It is also an encouragement upon not having many hopes and desires, stretching far into the future. Hence, one should not postpone till the morning actions that can be performed at night, but rather, one should hasten towards the performance of good actions. And similarly, when one wakes in the morning he should not rely upon the evening and postpone his good actions till then.
And his, radiAllaahu anhu, statement "Take from your health before times of sickness" is an encouragement upon making use of ones health, and striving ones utmost during times of good health, fearing the onset of sickness which may prevent one from good actions. And similarly, his statement "From your life before your death" is an admonition to make use of the days of ones life, since the one who dies has his actions cut off and his hopes lost. And then his distress will increase no end due to his neglect and previous lack of remorse. So let us know that a time will come when we will spend a great length of time under the dirt, unable to perform any action and unable to remember Allaah 'azza wa jall. So upon us is to hasten to good actions while we are still capable of doing so. And thus, what is more comprehensive and honourable than this hadeeth in its meanings of good ?
And some of the 'ulamaa have said that Allaah ta'aalaa has condemned having high hopes, as He has said :
And 'Alee radiAllaahu anhu said :
And Anas radiAllaahu anhu said : "The Prophet sallAllaahu alayhi wa sallam drew some lines [in the sand], and said 'This [line] is Man, and this is his hope, and [the third line, between them] is his appointed time for death. So while he is in this state the closer line takes him'", and that is his appointed hour of death, which contains and constrains his life. So this is a warning to him to lower his hopes, and to expect his appointed time to be near, and to always remain in fear that it may come while he is in a state of heedlessness and indulgence. So the Believer should accustom his soul to seeking those things which will remind him of his death, and he should strive against his desires and never-ending hopes, for verily Man is created with a disposition towards hope. 'Abdullaah bin 'Umar (radiAllaahu anhumaa) said : "The Messenger of Allaah, sallAllaahu alayhi wa sallam, saw me while I was strengthening with clay a shelter for my mother and myself, so he said 'What is this, O 'Abdullaah ?' So I replied : 'O Messenger of Allaah, it [the shelter] has become weak, and so we are repairing it'. So he (sallAllaahu alayhi wa sallam) said 'I do not see The Affair [ie Death or the Resurrection] except that it is closer than that [ie the falling apart of the shelter]'."
We ask Allaah the Glorious to show kindness to us and to help us abstain from the dunyaa, and to make us desire that which is with Him and ease on the Day of Resurrection, for verily He is the Generous, the Forgiving, the Merciful.
