عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم: لاَ يَتَمَنَّيَنَّ أَحَدٌ مِنْكُمُ الْمَوْتَ لِضُرٍّ نَزَلَ بِهِ، فَإِنْ كَانَ لاَ بُدَّ مُتَمَنِّيًا لِلْمَوْتِ فَلْيَقُلِ اللَّهُمَّ أَحْيِنِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي، وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي.
Hazrat Anasra narrated that “Allah’s Messengersa said, ‘None of you should wish for death because of a hardship that has befallen him. But if he finds himself compelled to wish for death, then he should say, ‘O Allah, keep me alive for as long as life is better for me and cause me to die when death is better for me.’’”
(Sahih al-Bukhari, Kitab ad-da‘awat, Bab ad-du‘a’i bi l-mawti wa l-hayat, Hadith 6351)
