This hadith was narrated by A'mash on the authority of the same chain of narrators and he said: One day the Messenger of Allah ﷺ climbed the hill of Safa' and said: Be on your guard, and the rest of the hadith was narrated like the hadith transmitted by Usama;
he made no mention of the revelation of the verse:" Warn thy nearest kindred."

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ قَالَ صَعِدَ رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ الصَّفَا فَقَالَ " يَا صَبَاحَاهْ " . بِنَحْوِ حَدِيثِ أَبِي أُسَامَةَ وَلَمْ يَذْكُرْ نُزُولَ الآيَةِ { وَأَنْذِرْ عَشِيرَتَكَ الأَقْرَبِينَ}
