Dua Before Salam in Salah (Invocations after the final Tash-ahhud and before ending the prayer, 9 of 11)

Allāhumma innī asʾaluka yā llāhu bi-annaka l-wāḥidu l-ʾaḥadu aṣ-ṣamadu alladhī lam yalid walam ywlad, walam yakn lahu kufūan aḥadun, an taghfira lī dhunūbī innaka anta l-ghafūru ar-raḥīm

O Allah, I ask You O Allah, as You are The One, The Only, AS-Samad, The One who begets not, nor was He begotten and there is none like unto Him that You forgive me my sins for verily You are The Oft-Forgiving, Most-Merciful.
