Narrated Abu Huraira (may Allah have mercy on him)
The Prophet (Sallallahu Alayhi wa Sallam) 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.”
Sahih Bukhari Volume 1, Book 2, Number 38
Prophet Muhammad (pbuh) said, "O people, spread the salaam (greetings), feed the hungry, and pray while the people are asleep, you will enter Jannah in peace."
The Prophet Muhammad (peace be upon him) was reported to have said: 'The most perfect Muslim in the matter of faith is one who has excellent behavior; and the best among you are those who behave best towards their wives"
