18. It is waajib (compulsory) for one to remain silent while the khutbah is being delivered e.g. Jumu‘ah, nikaah, eid, etc. If one speaks during the khutbah, one will be sinful.^[1]

عن ابن عباس قال: قال رسول الله صلى الله عليه وسلم: من تكلم يوم الجمعة والإمام يخطب فهو كمثل الحمار يحمل أسفارا والذي يقول له: أنصت ليس له جمعة رواه أحمد والبزار والطبراني في الكبير وفيه مجالد بن سعيد وقد ضعفه الناس ووثقه النسائي في رواية (مجمع الزوائد رقم 3123)

Hazrat ibnu ‘Abbaas (radhiyallahu ‘anhuma) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “The example of the one who speaks on the day of Jum‘uah while the Imaam delivers the khutbah is like that of a donkey which carries a load of books on its back (i.e. just as a donkey carrying a load of Deeni books on its back does not benefit from the Deeni books, similarly the one who speaks while the khutbah is in progress will not receive any benefit). And the one who asks another to remain silent (while the khutbah is being delivered), there is no Jumu‘ah for him (i.e. even though he is advising another to remain silent during the khutbah, he himself has committed a sin due to speaking while the khutbah is in progress).”
