I came to Khabbab who had been branded with seven brands(1) and he said, "Had Messenger of Allah ﷺ not forbidden us to invoke (Allah) for death, I would have invoked (Allah) for it."

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ

I came to Khabbab who had been branded with seven brands over his ʿAbdomen, and I heard him saying, "If the Prophet: had not forbidden us to invoke (Allah) for death, I would have invoked Allah for it."

أَتَيْتُ خَبَّابًا وَقَدِ اكْتَوَى سَبْعًا فِي بَطْنِهِ فَسَمِعْتُهُ يَقُولُ لَوْلاَ أَنَّ النَّبِيَّ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ

The Messenger of Allah ﷺ said, "None of you should long for death because of a calamity that had befallen him. But if he must long for death, then he should say:

allāhumma aḥyinī mā kānat al-ḥayātu khayran lī, wa-tawaffanī idhā kānat al-wafātu khayran lī

O Allah! Let me live as long as life is better for me, and take my life if death is better for me."

قَالَ رَسُولُ اللَّهِ ﷺ: «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)».
