the Messenger of Allah (ﷺ) said: "Whoever says: Subhan Allahi wa bi hamdihi (Glory and praise is to Allah) one hundred times, his sins will be forgiven even if they were like the foam of the sea.'"
Sunan Ibn Majah Book 33, Hadith 156
← Previous Hadith the Prophet (ﷺ) said: "(There are) four that are the best of words, and it does not matter with which you begin: Subhan-Allah, wal-Hamdu-Lillah, wa la ilaha illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshiped but Allah and Allah is the Most Great)."

Sunan Ibn Majah Book 33, Hadith 155 Next Hadith → "The Messenger of Allah (ﷺ) said to me: 'You should recite Subhan-Allah, wal-Hamdu-Lillah, wa la ilahah illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshiped but Allah, and Allah is the Most Great), for it sheds sins like the tree sheds its leaves.'"

Sunan Ibn Majah Book 33, Hadith 157
