The Apostle of Allah (may peace he upon him) came to Medina when I was ten years old and he died when I was twenty years old. My mother exhorted me to serve him. He (the Holy Prophet) came to our house, and we ruined a flabby goat for him and mixed it (the milk) with water from the well of the house. Messenger of Allah ﷺ drank that. Umar and Abu Bakr on his left side said to him: Messenger of Allah, give it to Abu Bakr, but he (the Holy Prophet) gave it to the desert Arab who was on his right. Messenger of Allah ﷺ said: He who is on the right, then he who is on the right. (Using translation from Muslim 2029b)
قَدِمَ النَّبِيُّ ﷺ وَأَنَا ابْنُ عَشْرٍ وَمَاتَ وَأَنَا ابْنُ عِشْرِينَ وَكُنَّ أُمَّهَاتِي تَحُثُّنِي عَلَى خِدْمَتِهِ فَدَخَلَ عَلَيْنَا فَحَلَبْنَا لَهُ مِنْ شَاةٍ دَاجِنٍ وَشِيبَ لَهُ مِنْ بِئْرٍ فِي الدَّارِ وَأَعْرَابِيٌّ عَنْ يَمِينِهِ وَأَبُو بَكْرٍ عَنْ يَسَارِهِ وَعُمَرُ نَاحِيَةً فَشَرِبَ رَسُولُ اللهِ ﷺ فَقَالَ عُمَرُ أَعْطِ أَبَا بَكْرٍ فَنَاوَلَ الْأَعْرَابِيَّ وَقَالَ الْأَيْمَنُ فَالْأَيْمَنُ
