حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنِي ابْنَ عُلَيَّةَ - عَنْ عَبْدِ الْعَزِيزِ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَتَمَنَّيَنَّ أَحَدُكُمُ الْمَوْتَ لِضُرٍّ نَزَلَ بِهِ فَإِنْ كَانَ لاَ بُدَّ مُتَمَنِّيًا فَلْيَقُلِ اللَّهُمَّ أَحْيِنِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي " .
English Translation
Anas (b. Malik) reported Allah's Messenger (ﷺ) as saying. None of you should make a request for death because of the trouble in which he is involved, but if there is no other help to it, then say:O Allah, keep me alive as long as there is goodness in life for me and bring death to me when there is goodness in death for me
