Abdullah bin Abbas reported,

Speak to the people once every Friday. If you refuse, then twice. If you wish to do more, then three times, but do not make people weary of this Quran. I should never find you coming to a group while they are engaged in a conversation of their own, then telling them stories, cutting off their discussion and wearying them. Instead, stay silent, and when they ask you, then speak to them while they desire it.Beware of rhymed phrasing in supplication and avoid it, for I witnessed the Messenger of Allah ﷺ and his companions doing nothing but that. Meaning, they did nothing but avoid it.

Sahih

عن ابن عباس قال

حدث الناس كل جمعة مرة، فإن أبيت فمرتين، فإن أكثرت فثلاث مرار، ولا تمل الناس هذا القرآن، ولا ألفينك تأتي القوم وهم في حديث من حديثهم، فتقص عليهم، فتقطع عليهم حديثهم، فتملهم ولكن أنصت، فإذا أمروك فحدثهم وهم يشتهونه، فانظر السجع من الدعاء فاجتنبه، فإني عهدت رسول الله ﷺ وأصحابه لا يفعلون إلا ذلك. يعني: لا يفعلون إلا ذلك الاجتناب.
