It is narrated from Sayyiduna Abu Umamah al-Bahili (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There are three kinds of people who are under the guarantee (responsibility) of Allah: a man who goes out to fight in the path of Allah; he is under Allah's guarantee until Allah takes his soul and admits him into Paradise, or brings him back with the reward and spoils he obtained. Second, a man who goes to the mosque; he is under Allah's guarantee until Allah takes his soul and admits him into Paradise, or brings him back with the reward and recompense he obtained. And third, a man who enters his house with a greeting of peace; he too is under Allah's guarantee." This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.
