Sahih Bukhari

The Prophet (ﷺ) said, "Religion is very easy and whoever overburdenshimself in his religion will not be able to continue in that way. Soyou should not be extremists, but try to be near to perfection andreceive the good tidings that you will be rewarded; and gain strengthby worshipping in the mornings, the afternoons, and during the last hours of the nights."
