عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنْ حَافَظَ عَلَى شُفْعَةِ الضُّحَى غُفِرَتْ لَهُ ذُنُوبُهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ))
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever regularly performs the two rak‘ahs of Duha prayer, all his sins will be forgiven, even if they are as much as the foam of the sea.
