Invocations after the final Tash-ahhud and before ending the prayer

اللَّهُمَّ إِنِّي أَسْأَلُكَ يَا أَللَّهُ بِأَنَّكَ الْوَاحِدُ الْأَحَدُ الصَّمَدُ الَّذِي لَمْ يَلِدْ وَلَمْ يولَدْ، وَلَمْ يَكنْ لَهُ كُفُواً أَحَدٌ، أَنْ تَغْفِرَ لِي ذُنُوبِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِّيمُ

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.
