“The Messenger of Allah ﷺ said: ‘Whoever regularly prays two Rak’ah of Duha, his sins will be forgiven even if they are like the foam of the sea.’” (Using translation from Ibn Mājah 1382)
قَالَ رَسُولُ اللهِ ﷺ مَنْ حَافَظَ عَلَى شُفْعَةِ الضُّحَى غُفِرَتْ ذُنُوبُهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ
