A’isha said:

"I saw Allah’s Messenger (ﷺ) when he was at the point of death, and beside him there was a vessel containing water. He would dip his hand into the vessel, then wipe his face with the water, saying: 'O Allah, help me against the atrocities of death (or: the agonies of death)!’”

حَدَّثَنَا قُتَيْبَةُ ‏,‏ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ الْهَادِ، عَنْ مُوسَى بْنِ سَرْجِسَ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ‏:‏ رَأَيْتُ رَسُولَ اللهِ صلى الله عليه وسلم، وَهُوَ بِالْمَوْتِ وَعِنْدَهُ قَدَحٌ فِيهِ مَاءٌ، وَهُوَ يُدْخِلُ يَدَهُ فِي الْقَدَحِ، ثُمَّ يَمْسَحُ وَجْهَهُ بِالْمَاءِ، ثُمَّ يَقُولُ‏:‏ اللَّهُمَّ أَعِنِّي عَلَى مُنْكَرَاتِ أَوْ قَالَ‏:‏ عَلَى سَكَرَاتِ الْمَوْتِ‏.‏
