Hisnul Muslim 254

Excellence of remembrance and glorification of Allah

سُبْحَانَ اللَّهِ وَبِحَمْدِهِ

Subhaanallaahi wa bihamdihi.

The Prophet (SAW) said: "Whoever says: "Glorified is Allah and praised is He" one hundred times a day, will have his sins forgiven even if they are like the foam of the sea".
