Sahih Muslim, 2930 c
sahih

Ibn 'Umar reported that Allah's Messenger (ﷺ) happened to pass by Ibn Sayyad along with his Companions including 'Umar b. Khattab as he was playing with children near the battlement of Bani Maghala and he was also a child by that time. The rest of the hadith is the same as narrated by Ibn Umar (in which there is a mention of) setting out of Allah's Messenger (ﷺ) along with Ubayy b. Ka'b towards the date-palm trees.

وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، وَسَلَمَةُ بْنُ شَبِيبٍ، جَمِيعًا عَنْ عَبْدِ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مَرَّ بِابْنِ صَيَّادٍ فِي نَفَرٍ مِنْ أَصْحَابِهِ فِيهِمْ عُمَرُ بْنُ الْخَطَّابِ وَهُوَ يَلْعَبُ مَعَ الْغِلْمَانِ عِنْدَ أُطُمِ بَنِي مَغَالَةَ وَهُوَ غُلاَمٌ ‏.‏ بِمَعْنَى حَدِيثِ يُونُسَ وَصَالِحٍ غَيْرَ أَنَّ عَبْدَ بْنَ حُمَيْدٍ لَمْ يَذْكُرْ حَدِيثَ ابْنِ عُمَرَ فِي انْطِلاَقِ النَّبِيِّ صلى الله عليه وسلم مَعَ أُبَىِّ بْنِ كَعْبٍ إِلَى النَّخْلِ ‏.‏
