Sahih Bukhari 6405: How to get all SINS Forgiven?

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.
