Authentic Supplication Number 086.

And in the hadeeth of Ali  about the salat of the Messenger of Allah : and when he would bow he would say in his bowing: 'Allahumma laka raka`tu, wabika amentu, walaka 'aslamtu, khasha`a laka sam`ee, wa basaree, wa mukhkhee, wa `athmee, wa `asabee (99). When he would lift his head from the bowing he would say: Sami`al-lahu liman hamidahu, rabbana walakal hamdu, mil'as-samawati, wa mil'al-'ardhi, wa mil'a ma baynahuma, wa mil'a ma shi'ta min shay'in ba`du, (100) and when he would have prostrated he would say in his prostration: 'Allahumma laka sajadtu, wabika amentu, walaka 'aslamtu, sajada wajhee lil-lathee khalaqahu wa sawwarahu, wa shaqqa sam`ahu, wa basarahu, tabarakal-lahu 'ahsanul khaliqeena (101).

Footnotes.
(99) O' my 'ilah to You I have bowed, and in You I have cammitted faith, and before Thee my hearing, my sight, my marrow, my bones, and my nerves have humbled [surrendered in complete fear, humility, and obedience to You].

(100) Allah hears the one that praises Him! You are our Lord and to You is all praise, as much as would fill the Heavens, as much as would fill the Earth, as much as would fill that which is in between them, and as much as would fill what ever You will of anything [else] thereafter.

(101) O' my 'ilah to You I have prostrated, and in You I have committed faith, and to You I have surrendered. My face has prostrated to the One that has created it, fashioned it, and slit for it its hearing and its sight. Blessed is Allah best of creators.
