Sahih Bukhari 1185

حَدَّثَنِي إِسْحَاقُ ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ ، حَدَّثَنَا أَبِي ، عَنِ ابْنِ شِهَابٍ , قَالَ : أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ الْأَنْصَارِيُّ ، أَنَّهُ عَقَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَعَقَلَ مَجَّةً مَجَّهَا فِي وَجْهِهِ مِنْ بِئْرٍ كَانَتْ فِي دَارِهِمْ .

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.
