Sunan an-Nasa'i, 1050

It was narrated from Ali bin Abi Talib that:When the Messenger of Allah (ﷺ) bowed, he said: "Allahumma laka rak`atu was laka aslamtu wa bika amantu, khasha`a laka sam`i wa basri wa `izami wa mukhi wa `asabi (O Allah, to You I have bowed and to You I have submitted and in You I have believed. My hearing, sight, bones, brain and sinews are humbled before You)

Rapporté par Ali bin Abi Talib : Quand le Messager d’Allah (ﷺ) s’inclinait, il disait : « Allahumma laka rak‘atu, wa laka aslamtu, wa bika amantu, khasha‘a laka sam‘i wa basri wa ‘izami wa mukhi wa ‘asabi » (« Ô Allah, c’est devant Toi que je m’incline, c’est à Toi que je me soumets et en Toi que je crois. Mon ouïe, ma vue, mes os, mon cerveau et mes nerfs s’humilient devant Toi »)
