Narrated Al-Mughira:

The Prophet said, "Allah has forbidden you ( 1 ) to be undutiful to your mothers (2) to withhold (what you should give) or (3) demand (what you do not deserve), and (4) to bury your daughters alive. And Allah has disliked that (A) you talk too much about others ( B), ask too many questions (in religion), or (C) waste your property."
