General Behavior (Kitab Al-Adab)
Dawud :: Book 41 : Hadith 4782
Narrated AbuUmamah:
The Prophet (peace_be_upon_him) said: I guarantee a house in the surroundings of Paradise for a man who avoids quarrelling 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.
