Chapter 31: The Book of Judicial Decisions
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.
Sahih Muslim 593h
