Abu Umamah narrated:
The Prophet (peace be upon him) said:
i guarantee a house in the surroundings of paradise for a man who avoids quarreling even if he were in the right, a house in the middle of paradise for a man who avoids lying even if he were joking, and a house in the upper part of paradise for a man who made his character good.
[Abu Dawud Book 41, Hadith 4782.
