Sunan an-Nasa'i, 1057

Rapporté par Salim, d’après son père : Le Messager d’Allah (ﷺ) levait les mains jusqu’à la hauteur de ses épaules au début de la prière, et quand il relevait la tête de l’inclinaison, il faisait de même. Quand il disait : Sami' Allahu liman hamidah (Allah entend celui qui Le loue), il disait : « Rabbana wa lakal-hamd (Notre Seigneur, à Toi la louange) », et il ne levait pas les mains entre les deux prosternations

It was narrated from Salim, from his father, that:The Messenger of Allah (ﷺ) used to raise his hands until they were in level with his shoulders when he started to pray, and when he raised his head from bowing he did likewise, and when he said: Sami' Allahu liman hamidah (Allah hears the one who praises Him)" he said: "Rabbana wa lakal-hamd (Our Lord, to You be praise)" and he did not raise his hands between the two prostrations
