Then onceلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِٱللَّهِ ٱلْعَليِّ ٱلْعَظِيمِla hawla wala quwwata illa billahil aliyy'al azeemThere is no power and no strength except with Allah, the Most High, the All-great. Then onceيَا عَزِيزُ يَا غَفَّارُٱغْفِرْ لِي ذُنُوبِي وَذُنُوبَ جَمِيعِ ٱلْمُؤْمِنِينَ وَٱلْمُؤمِنَاتِفَإِنَّهُ لاَ يَغْفِرُ ٱلذُّنُوبَ إِلاَّ انْتَYa azeezu ya ghaffarighfir le dhunubi wa dhunuba jameea al mumeneena wal mumnenaati Fa inna hu la yaghfiru aldhunuba illa antaO Almighty! O All-forgiving!(Please) forgive my sins and the sins of all believing men and women, for none can forgive sins save You. so based on the hadith above, can I just do wudu and preform the prayer, or is it wajib to do ghusl for this prayer?
