Sahih Muslim, 1057

Rapporté par Al-Bara' b. 'Azib : J’ai observé la prière de Muhammad ﷺ et j’ai vu que sa station debout, son inclinaison, le retour à la station debout après l’inclinaison, sa prosternation, son assise entre les deux prosternations, ainsi que sa prosternation et son assise entre la salutation et le départ, tout cela était presque de durée égale

Al-Bara' b. 'Azib reported:I noticed the prayer of Muhammad (ﷺ) and saw his Qiyam (standing), his bowing, and then going back to the standing posture after bowing, his prostration, his sitting between the two prostrations, and his prostration and sitting between salutation and going away, all these were nearly equal to one another
