Dua 9
اَللّٰهُمَّ اِنِّيْٓ اَسْئَلُكَ يَآ اَللّٰهُ بِاَنَّكَ الْوَاحِدُ الْاَحَدُ الصَّمَدُ الَّذِيْ لَمْ يَلِدْ وَلَمْ يُوْلَدْ وَلَمْ يَكُنْ لَهٗ كُفُوًا اَحَدٌ اَنْ تَغْفِرَ لِيْ ذُنُوْبِيْ اِنَّكَ اَنْتَ الْغَفُوْرُ الرَّحِيْمُ
O Allah! I ask You, O Allah, because You are the One, the Unique, the Self-Sufficient Master, who neither begets nor is born, and to whom none is equal. (I ask You) to forgive me my sins. Indeed, You are the Most Forgiving, the Most Merciful.
