((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)).
(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.)(AS-Samad: The Self-Sufficient Master, Possessor of perfect attributes whom all of creation turn to in all their needs.)
