Abu Umamat Al Bahili reported the Messenger of Allah ﷺ as saying “There are three persons who are in the security of Allaah, the Exalted. ” “A man who goes out on an expedition to fight in the path of Allaah, the Exalted, is in the security of Allaah, until He takes him unto Him (i. e., he dies) and brings him into Paradise or brings him (alive) with reward and booty he obtains and a man who goes to the mosque is in the security of Allaah, until he takes him unto Him (i. e., he dies), and he brings him into Paradise or brings him with reward and spoils he obtains; and a man who enters his house after giving salutation is in the security of Allaah, the Exalted. ”

Narrated Abu Umamah: The Prophet ﷺ 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.
