Sayyiduna Abu Ju’d Damri, may Allah be pleased with him, is a companion of the Messenger. He narrates: The Prophet Muhammad, peace and blessings be upon him, said:“Whoever, out of disregard, abandons Friday (prayer) three times, Allah Almighty will set a seal upon his heart.”

Sayyiduna Abu Hurairah, may Allah be pleased with him, narrates this statement of the Prophet Muhammad, peace and blessings be upon him: "When a servant commits a mistake, a dot is placed upon his heart. If he separates himself from it, seeks forgiveness, and repents, then that dot is cleansed. However, if he repeats the same mistake, then it increases. If he commits the mistake again, then it increases further, until (that darkness) overcomes his heart. This is the rust which Allah, the Exalted, has mentioned: 'Rather, a rust has covered their hearts because of what they used to earn.'"

Sayyiduna Samurah bin Jundub (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) said: "Whoever misses Jumu'ah should give one dinar in charity, and if he cannot afford it, then he should give half a dinar."

Sayyiduna Samurah bin Jundub (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever leaves Jumu'ah (Friday prayer) without an excuse should give one dinar in charity; if that is not available, then half a dinar."

Sayyiduna Abdullah bin Busr (may Allah be pleased with him) narrates: I was sitting beside the pulpit on Friday when a man came and began stepping over people's necks while the Prophet Muhammad (peace and blessings be upon him) was delivering the sermon. The Prophet Muhammad (peace and blessings be upon him) said to him: Sit down, you have caused harm and you came late.

Abu Wa'il narrates: Sayyiduna Ammar bin Yasir (may Allah be pleased with him) delivered a brief and eloquent sermon to us. When he descended from the pulpit, we said: O Abu Yaqzan! You delivered an eloquent and brief sermon; if you had given a longer (sermon), it would have been appropriate. He replied: I heard the Noble Prophet (peace and blessings be upon him) say this: "A man's prolonging of the prayer and shortening of the sermon is a sign of his understanding. So, you people should prolong the prayer and shorten the sermon, for some speech is (as effective as) magic."

Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "When a person becomes drowsy while sitting in his place on the day of Jumu'ah, he should move to another place."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "When you say to your companion during the Imam's sermon, 'Be quiet,' then you have engaged in idle talk."

Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) entered the mosque while the Prophet (peace and blessings of Allah be upon him) was delivering the sermon. He sat beside Sayyiduna Ubayy bin Ka’b (may Allah be pleased with him). He asked him about something, or spoke to him about something, but Sayyiduna Ubayy (may Allah be pleased with him) did not answer him. Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) thought perhaps Sayyiduna Ubayy bin Ka’b (may Allah be pleased with him) was upset about something. When the Prophet (peace and blessings of Allah be upon him) finished the prayer, Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) said: O Ubayy! What is the reason you did not answer me? Sayyiduna Ubayy (may Allah be pleased with him) said: You did not join us in the Friday (congregation). Sayyiduna Abdullah (may Allah be pleased with him) asked: Why is that? Sayyiduna Ubayy (may Allah be pleased with him) said: The reason is that you spoke during the sermon of the Prophet (peace and blessings of Allah be upon him). So Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) stood up and went to the Prophet (peace and blessings of Allah be upon him) and mentioned this matter before him. The Prophet (peace and blessings of Allah be upon him) said to him: Ubayy has spoken the truth; follow what Ubayy has said. These are the words as narrated by Abdul A’la.

Sayyiduna Abu Hurairah, may Allah be pleased with him, narrates this statement of the Prophet, peace and blessings be upon him: "When a person says to his companion 'Be quiet' while the Imam is delivering the sermon, then he has engaged in idle talk." Ibn Jurayj states: The same narration is transmitted through another chain from Sayyiduna Abu Hurairah, may Allah be pleased with him.
