One hundred SubhanAllah
مَنْ قَالَ: سُبْحَانَ اللَّهِ وَبِحَمْدِهِ فِي يَوْمٍ مِائَةَ مَرَّةٍ، حُطَّتْ خَطَايَاهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ
Man qala: SubhanAllahi wa bi-hamdih fi yawmin mi'ata marrah, huttat khatayahu wa in kanat mithla zabadi-l-bahr.
"Whoever says, SubhanAllah wa bi-hamdih, a hundred times in a day, his sins are wiped away even if they were like the foam of the sea."
Narrated by Abu Hurayrah. Sahih al-Bukhari 6405, Sahih Muslim 2691
A short reflection
Four words. One hundred reps. Two minutes total. Foam of the sea, wiped. We pay more for less every day.
