It was narrated that Ibn ‘Abbas said:
“The Messenger of Allah ﷺ was brought some milk. On his right was Ibn ‘Abbas and on his left was Khalid bin Walid. The Messenger of Allah ﷺ said to Ibn ‘Abbas: ‘Will you permit me to give Khalid to drink?’ Ibn ‘Abbas said: ‘I would not like to give preference to anyone over myself when it comes to the leftover drink of the Messenger of Allah ﷺ. So Ibn ‘Abbas took it and drank some, then Khalid drank some.”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، حَدَّثَنَا ابْنُ جُرَيْجٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أُتِيَ رَسُولُ اللَّهِ ﷺ بِلَبَنٍ وَعَنْ يَمِينِهِ ابْنُ عَبَّاسٍ وَعَنْ يَسَارِهِ خَالِدُ بْنُ الْوَلِيدِ فَقَالَ رَسُولُ اللَّهِ ﷺ لاِبْنِ عَبَّاسٍ " أَتَأْذَنُ لِي أَنْ أَسْقِيَ خَالِدًا " . قَالَ ابْنُ عَبَّاسٍ مَا أُحِبُّ أَنْ أُوثِرَ بِسُؤْرِ رَسُولِ اللَّهِ ﷺ عَلَى نَفْسِي أَحَدًا . فَأَخَذَ ابْنُ عَبَّاسٍ فَشَرِبَ وَشَرِبَ خَالِدٌ .
