Narrated by Abu Huraira (Radiallahu anhu):
The Prophet (pbuh) said, "Religion is very easy and whoever overburdens himself in his religion will not be able to continue in that way. So you should not be extremists, but try to be near to perfection and receive the good tidings that you will be rewarded; and gain strength by worshipping in the mornings, the nights."

[Bukhari Vol. 1, Book 2, Number 38]

Narrated by Abu Huraira (Radiallahu anhu):
The Prophet (pbuh) 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."
