وَعَن أنسٍ قَالَ: حُلِبَتْ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَاةٌ دَاجِنٌ وَشِيبَ لَبَنُهَا بِمَاءٍ مِنَ الْبِئْرِ الَّتِي فِي دَارِ أَنَسٍ فَأُعْطِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْقَدَحَ فَشَرِبَ وَعَلَى يَسَارِهِ أَبُو بَكْرٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ فَقَالَ عُمَرُ: أَعْطِ أَبَا بَكْرٍ يَا رَسُولَ اللَّهِ فَأَعْطَى الْأَعْرَابِيَّ الَّذِي عَنْ يَمِينِهِ ثُمَّ قَالَ: " الْأَيْمَنُ فَالْأَيْمَنُ وَفِي رِوَايَةٍ: «الْأَيْمَنُونَ الْأَيْمَنُونَ أَلاَ فيَمِّنوا»
Anas reported: A domesticated sheep was milked for the Messenger of Allah ﷺ, and its milk was mixed with water from the well in the house of Anas. The cup was given to the Messenger of Allah ﷺ, and he drank. Abu Bakr was on his left, and a Bedouin on his right. Umar said, “Give it to Abu Bakr, Messenger of Allah.” But he gave it to the Bedouin on his right, then said, “The one on the right, then the one on the right.” Another version says, “Those on the right, those on the right; let them be given precedence.”
