خرج رسول الله ﷺ وأسلم يرمون فقال: ارموا بني إسماعيل؛ فإن أباكم كان راميا، وارموا وأنا مع ابن الأدرع، فأمسك القوم قسيهم وقالوا: من كنت معه غلب. قال: ارموا، وأنا معكم كلكم.
Abu Yaala narrated it (6119), and Ibn Hibban graded it sahih (4695), as did Hakim (2/94), all of them through routes from Muhammad bin Amr bin Alqama, from Abu Salama, from Abu Hurairah, who narrated it as mentioned.Hakim said, "It is sahih according to the criteria of Muslim."I say, its chain of transmission is hasan because of Muhammad bin Amr bin Alqama, for his hadith is hasan.
