It was narrated from Ibn Abbas that: when the Prophet came to Makkah, he was welcomed by the boys of Banu Hashim, and he carried one of them in front of him (on his mount) and one behind him.
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا يَزِيدُ، - وَهُوَ ابْنُ زُرَيْعٍ - عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم لَمَّا قَدِمَ مَكَّةَ اسْتَقْبَلَهُ أُغَيْلِمَةُ بَنِي هَاشِمٍ - قَالَ - فَحَمَلَ وَاحِدًا بَيْنَ يَدَيْهِ وَآخَرَ خَلْفَهُ .
