A hundred words that weigh more than they look
Said a hundred times in a day, and sins fall away though they were like the foam of the sea.
مَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ. فِي يَوْمٍ مِائَةَ مَرَّةٍ حُطَّتْ خَطَايَاهُ، وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ
Subḥāna-llāhi wa bi-ḥamdih. (×100)
“Glory be to Allah, and praise Him.”
The full narration
Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "Whoever says, 'Subhan Allah 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
