Prayer › Supplication said after the last tashahhud and before salam
Dua before salam — I have wronged myself, forgive me
اللَّهُـمَّ إِنِّـي ظَلَـمْتُ نَفْسِـي ظُلْمًـا كَثِـيرًا وَلَا يَغْـفِرُ الذُّنُـوبَ إِلَّا أَنْتَ ، فَاغْـفِرْ لِـي مَغْـفِرَةً مِـنْ عِنْـدِكَ وَارْحَمْـنِي، إِنَّـكَ أَنْـتَ الْـغَفُـورُ الرَّحِـيمُ
Allāhumma innī ẓalamtu nafsī ẓulman kathīran wa lā yaghfiru dh-dhunūba illā ant, fa-ghfir lī maghfiratan min ‘indik wa rḥamnī, innaka anta l-ghafūru r-raḥīm.
Translation
O Allah, I have indeed oppressed my soul excessively and none can forgive sin except You, so forgive me a forgiveness from Yourself and have mercy upon me. Surely, You are The Most-Forgiving, The Most-Merciful.
When to recite
In prayer, after the final tashahhud and before the closing salam.
Footnote
From Yourself: i.e., from Your innermost grace without deserving it and a forgiveness which is befitting to your tremendous generosity.
