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 ( صلی اللہ علیہ وسلم ) 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."
