Narrated Ash−Shu`bi: The clerk of Al−Mughira bin Shu`ba narrated,
“Muawiya wrote to Al−Mughira bin Shu`ba: Write to me something which you have heard from the Prophet (p.b.u.h) .” So Al−Mughira wrote:
I heard the Prophet 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).
