385.Narrated Abu Huraira (Allah be pleased with him): The Prophet (peace be upon him) 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, afternoons and during the last hours of the nights."
(Sahih Al-Bukhari Vol 1).
