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.  

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
