"The Messenger of Allah said: 'Do not pray for death or wish for it. Whoever insists on praying for it let him say: Allahumma ahini ma kanatil-hayatu khairanli wa tawaffani idha kanatil-wafatu khairanli (O Allah, keep me alive so long as life is good for me, and cause me to die when death is good for me.)"'  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَدْعُوا بِالْمَوْتِ وَلاَ تَتَمَنَّوْهُ فَمَنْ كَانَ دَاعِيًا لاَ بُدَّ فَلْيَقُلِ اللَّهُمَّ أَحْيِنِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي  

"I entered upon Khabbab when he had been cauterized on his stomach seven times. He said: 'Were it not that the Messenger of Allah forbade us to pray for death, I would have prayed for it."'  

دَخَلْتُ عَلَى خَبَّابٍ وَقَدِ اكْتَوَى فِي بَطْنِهِ سَبْعًا وَقَالَ لَوْلاَ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ دَعَوْتُ بِهِ
