Narrated Abu Huraira radiallahu anhu:

Allah's Messenger peace be upon him said, "If any one of you improve (follows strictly) his Islamic religion then his good deeds will be rewarded ten times to seven hundred times for each good deed and a bad deed will be recorded as it is (without increase)"

In this hadith, the Prophet peace be upon him encourage Ummah to become admirer Muslim in religion. No one can beautify his Islam unless he is a very devoted Muslim. When a person beautifies his Islam, he will receive a great reward:

1. Every good deed he does is multiplied ten to seven hundred times.

2. Every evil that he has done will be recorded in the same way (without increase), and will be forgiven if Allah so wills. This indicates that the believer reaches the highest levels.
