Hadith
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ
مَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ. فِي يَوْمٍ مِائَةَ مَرَّةٍ حُطَّتْ خَطَايَاهُ، وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ ”
Narrated Abu Huraira:
Rasuullah Sallallahu Alaihi Wa Sallam said,
“Whoever says, ‘Subhanallahi Wa Bihamdihi,’ one hundred times a day, will be forgiven all his sins even if they were as much as the foam of the sea.
