Sahih Muslim 2930c
Ibn 'Umar reported that Messenger of Allah 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 Apostle 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 ﷺ 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 ﷺ مَعَ أُبَىِّ بْنِ كَعْبٍ إِلَى النَّخْلِ .
