Sahih Al Bukhari (188)

وَقَالَ أَبُو مُوسَى: دَعَا النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ بِقَدَحٍ فِيهِ مَاءٌ، فَغَسَلَ يَدَيْهِ وَوَجْهَهُ فِيهِ، وَمَجَّ فِيهِ، ثُمَّ قَالَ لَهُمَا: «اشْرَبَا مِنْهُ، وَأَفْرِغَا عَلَى وُجُوهِكُمَا وَنُحُورِكُمَا»

Abu Burda reported that Abu Musa said: "I was with the Prophet (peace be upon him) when he was encamping at Al Ja`ranah (a place) between Makkah and Medina and Bilal was with him. A bedouin came to the Prophet (peace be upon him) and said: "Won't you fulfill what you have promised me?" The Prophet (peace be upon him) said: 'Rejoice (at what I will do for you).' The bedouin said: "(You have said to me) rejoice too often." Then the Prophet (peace be upon him) turned to me (i.e. Abu Musa) and Bilal in an angry mood and said: 'The bedouin has refused the good tidings, so you both accept them.' Bilal and I said: 'We accept them.' Then the Prophet (peace be upon him) asked for a drinking bowl containing water and washed his hands and face in it, and then took a mouthful of water and threw it therein saying (to us), "Drink (some of) it and pour (some) over your faces and chests and be happy at the good tidings." So, they both took the drinking bowl and did as instructed. Um Salamah called from behind a screen: "Keep something (of the water) for your mother." So, they left some of it for her.
