Sha'bi reported that the scribe of al-Mughirah bin Shu'bah said: Mu'awiyah wrote to Mughira: Write for me something which you heard from Allah's Messenger (ﷺ); and he wrote: I heard Allah's Messenger (ﷺ) as saying. Verily Allah disapproves three things for you: irrelevant talk, wasting of wealth and persistent questioning.
