Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) says: When the day of Friday comes, the devils go out carrying their flags and stop people towards the markets, while the angels sit at the doors of the mosques and begin to write the people according to their ranks, that is, the one who comes first, then the one who comes second, then the one who comes after him, (this sequence continues) until the Imam comes out. So whoever sits close to the Imam, listens to the sermon attentively and silently, and does not engage in any idle act, for him there are two rewards. And whoever sits far from the Imam, but listens to the sermon attentively, remains silent, and does not engage in any idle act, for him there is one reward. And whoever sits close to the Imam, but engages in idle acts and neither remains silent nor listens to the sermon attentively, upon him are two portions of sin. And whoever sits far from the Imam, engages in idle acts, neither remains silent nor listens to the sermon attentively, upon him is one portion of sin. And whoever says to someone, "Be silent," then he has spoken, and whoever has spoken, his Friday (Jumu'ah) is not valid. Then Sayyiduna Ali (may Allah be pleased with him) said: I heard the Noble Prophet (peace and blessings be upon him) say this in the same way.
