It is narrated from (the paternal uncle of Muhammad bin Abd al-Rahman) (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever hears the call (adhan) on Friday and does not come (to the prayer), or (the narrator is unsure whether he (peace and blessings be upon him) said) does not respond to the call, then hears the adhan again and does not come or does not respond, then hears the adhan a third time and does not come or does not respond, Allah, the Mighty and Majestic, seals his heart, and his heart is made the heart of a hypocrite."
