A man of the Ansar quoting from his father said that the Prophet ﷺ called for a skin-vessel on the day of the battle of Uhud. He then said:

Invert the head of the vessel and he drank from its mouth.

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ، عَنْ عِيسَى بْنِ عَبْدِ اللَّهِ، - رَجُلٍ مِنَ الأَنْصَارِ - عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ دَعَا بِإِدَاوَةٍ يَوْمَ أُحُدٍ فَقَالَ " اخْنُثْ فَمَ الإِدَاوَةِ " . ثُمَّ شَرِبَ مِنْ فِيهَا .
