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 صلى الله عليه وسلم دَعَا بِإِدَاوَةٍ يَوْمَ أُحُدٍ فَقَالَ ‏"‏ اخْنُثْ فَمَ الإِدَاوَةِ ‏"‏ ‏.‏ ثُمَّ شَرِبَ مِنْ فِيهَا ‏.‏
