Sayyiduna Ibn Abi Awfa (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever hears the call (adhan) on Friday and does not attend Jumu'ah, then hears the call (the next Friday) and does not attend it, and this happens three times, a seal is placed upon that person's heart, and his heart is made the heart of a hypocrite."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator who could not be identified.
