Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrated that he passed by Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), who was sitting in front of the door of his house making gestures with his hands, as though he were talking to himself. Abdullah said: O Abu Abd al-Rahman, are you talking to yourself? He said: The enemy of Allah wants to make me heedless of words I heard from the Messenger of Allah (peace and blessings be upon him). Abdullah said: You are now enduring the hardships of your days in your house; why do you not go out to the gathering and talk? Mu'adh (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever goes out for jihad in the way of Allah, Allah is his guarantor; whoever stays in his house without speaking ill of anyone, that is, without backbiting, Allah is his guarantor too; whoever visits the sick, or goes to the mosque in the morning or evening, Allah is their guarantor too; and whoever supports the imam, Allah is his guarantor too." The enemy of Allah wanted to draw me out of my house to the gathering.
