Narrated Mahmud bin Ar-rabi' Al-Ansari,

that he remembered Allah's Apostle and he also remembered a mouthful of water which he had thrown on his face, after taking it from a well that was in their house.

حَدَّثَنِي إِسْحَاقُ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبِي، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ الأَنْصَارِيُّ، أَنَّهُ عَقَلَ رَسُولَ اللَّهِ ﷺ، وَعَقَلَ مَجَّةً مَجَّهَا فِي وَجْهِهِ مِنْ بِئْرٍ كَانَتْ فِي دَارِهِمْ.
