Abu Umamah Al-Bahili (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said,
“I guarantee a house in Jannah for one who gives up arguing, even if he is in the right; and I guarantee a home in the middle of Jannah for one who abandons lying even for the sake of fun; and I guarantee a house in the highest part of Jannah for one who has good manners.
[Abu Dawud,4800]
