Sha'bi reported that the scribe of al-Mughira b. Shu'ba said:Mu'awiya 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 thingq for you: irrelevant talk, wasting of wealth and persistent questioning
