The deed which is done seeking Allah's Countenance
حَدَّثَنَا مُعَاذُ بْنُ أَسَدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ، وَزَعَمَ، مَحْمُودٌ أَنَّهُ عَقَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم وَقَالَ وَعَقَلَ مَجَّةً مَجَّهَا مِنْ دَلْوٍ كَانَتْ فِي دَارِهِمْ.
Narrated Mahmud bin Ar-Rabi'a: I remember that the Allah's Messenger (ﷺ) took water from a bucket (which was in our home used for getting water out of well) with his mouth (and threw it on my face).
