Ibrahim reported,

Aswad and Alqama were with Abdullah in the house when Abdullah asked, "Have these people prayed?"They replied, "Yes."So he led them in prayer without adhan or iqama, standing in the middle of them. He then said, "When you are three, do as I have done. When you are more than that, let one of you lead the others. And when one of you bows, let him place his hands between his thighs and bend forward. It is as if I can still see the spaces between the fingers of the Messenger of Allah ﷺ."

Ahmad 4272

Sahih

حدثنا محمد بن جعفر حدثنا شعبة عن سليمان

عن إبراهيم

أن الأسود وعلقمة كانا مع عبد الله في الدار فقال عبد الله صلى هؤلاء قالوا نعم قال فصلى بهم بغير أذان ولا إقامة وقام وسطهم وقال إذا كنتم ثلاثة فاصنعوا هكذا فإذا كنتم أكثر فليؤمكم أحدكم وليضع أحدكم يديه بين فخذيه إذا ركع فليحنأ فكأنما أنظر إلى اختلاف أصابع رسول الله ﷺ
