Allāhumma laka sajadtu
wa bika āmantu,
wa laka aslamtu,
sajada waj’hiya lilladhī khalaqahu, wa ṣawwarahu,
wa shaqqa sam`ahu wa baṣarahu,
tabārakallāhu 'aḥsanul-khāliqīn.
O Allah, to You I prostrate myself and in You I believe.
To You I have submitted.
My face is prostrated to the One Who created it, fashioned it, and gave it hearing and sight.
Blessed is Allah, the Best of creators
