"None of you should wish for death because of some harm that befalls him, rather he should say: 'Allahumma ahini ma kanatil-hayatu khairanli wa tawaffani idha kanatil-wafatu khairanli (O Allah, keep me alive so alive so long as life is good for me, and cause me to die when death is good for me.)"'
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَتَمَنَّيَنَّ أَحَدُكُمُ الْمَوْتَ لِضُرٍّ نَزَلَ بِهِ فِي الدُّنْيَا وَلَكِنْ لِيَقُلِ اللَّهُمَّ أَحْيِنِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي
