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."
صَعِدَ رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ الصَّفَا فَقَالَ يَا صَبَاحَاهْ بِنَحْوِ حَدِيثِ أَبِي أُسَامَةَ وَلَمْ يَذْكُرْ نُزُولَ الآيَةِ { وَأَنْذِرْ عَشِيرَتَكَ الأَقْرَبِينَ}
