Hazrat Abu Huraira, Allah be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said:
“Religion is very easy. 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 afternoons and during the last hours of the nights.”
(Sahih al-Bukhari, Kitab-ul-Iman)
