Narrated Ash-sha’bi (Radhiallahu ‘anhu):
The clerk of Al-Mughira bin Shu’ba narrated, “Muawiya wrote to Al-Mughira bin Shu’ba (RadhiAllahu ‘anhuma): Write to me something which you have heard from the Prophet (Sallallaahu ‘alaihi wasallam).”
So Al-Mughira (Radhiallahu ‘anhu) wrote: I heard the Prophet (Sallallaahu ‘alaihi wasallam) saying, “Allah has hated for you three things:
1. Vain talks, (useless talk) that you talk too much or about others.
2. Wasting of wealth (by extravagance)
3. And asking too many questions (in disputed religious matters) or asking others for something (except in great need)
