Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah

Narrated Abu Huraira (Radi-Allahu ‘anhu):

The Prophet (Sallallahu ‘Alaihi Wa Sallam) said, “Whoever fasted the month of Ramadan out of sincere Faith (i.e. belief) and hoping for a reward from Allah, then all his past sins will be forgiven, and whoever stood for the prayers in the night of Qadr out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven .”
