Mishkat al-Masabih #237

Ikrima reported Ibn ‘Abbas as saying, “Talk to the people once every Friday, but if you object, then twice, and if you want more, then three times, but do not weary the people with this Qur’an. And do not let me find you coming to the people when they are talking about their concerns, interrupting them in their talk by addressing them, and so wearying them. Keep silent, and when they request you, talk to them at a time when they want it. Look out for rhymed prose in supplications and avoid it, for I know that God’s messenger and his companions did not use it.” Bukhari transmitted it.
