In the Name of Allah, The Most Gracious, The Most Merciful
They have not appraised Allah with true appraisal. Indeed, Allah is Powerful and Exalted in Might. Allah chooses from the angels messengers and from the people. Indeed, Allah is Hearing and Seeing. He knows what is [presently] before them and what will be after them. And to Allah will be returned [all] matters. O you who have believed, bow and prostrate and worship your Lord and do good - that you may succeed. And strive hard for Allah with the striving due to Him. He has chosen you and has not placed upon you in the religion any hardship. It is the religion of your father, Ibrahim (Abraham). Allah named you "Muslims" both before and (in former scriptures] and in this [The Qur’an] that the Messenger may be a witness over you and you may be witnesses over the people. So establish prayer and give zakah and hold fast to Allah. He is your protector; and what a excellent protector, and what a excellent is the helper.- The Holy Qur’an 22:74-78
Narrated Abu Huraira (RA):
The Prophet(SWS) 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." - Shahi Bukhari Vol. 1 No. 38.
