Volume 8, Book 75, Number 349:
Narrated ‘Ikrima:
Ibn ‘Abbas said, “Preach to the people once a week, and if you won’t, then preach them twice, but if
you want to preach more, then let it be three times (a week only), and do not make the people fed-up
with this Qur’an. If you come to some people who are engaged in a talk, don’t start interrupting their
talk by preaching, lest you should cause them to be bored. You should rather keep quiet, and if they
ask you, then preach to them at the time when they are eager to hear what you say. And avoid the
use of rhymed prose in invocation for I noticed that Allah’s Apostle and his companions always
avoided it.”
