Sunan Ibn Majah, Hadith 4265 ⓘ
4265 It was narrated from Anas that the Messenger of Allah said: “None of you should wish for death because of some harm that befalls him. If he must wish for death, let him say: ‘O Allah, keep me alive so long as living is good for me and cause me to die when death is good for me.’”
حَدَّثَنَا عِمْرَانُ بْنُ مُوسَى اللَّيْثِيُّ، حَدَّثَنَا عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ صُهَيْبٍ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ : " لاَ يَتَمَنَّى أَحَدُكُمُ الْمَوْتَ لِضُرٍّ نَزَلَ بِهِ فَإِنْ كَانَ لاَ بُدَّ مُتَمَنِّيًا الْمَوْتَ فَلْيَقُلِ : اللَّهُمَّ أَحْيِنِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي " .
