- It is prohibited to speak while listening to the sermon, even to forbid something wrong, return a greeting, or say tashmīt (saying: may Allah show mercy to you) to someone who has sneezed.
- Excluded from this is a person who speaks to the Imām or the Imām speaks to him.
- It is permissible to speak between the two sermons if needed.
- If mention of the Prophet (may Allah's peace and blessings be upon him) is made while the Imām is delivering the sermon, you should invoke Allah's blessings upon him inaudibly. The same holds for saying 'amen' after supplications.
