Sahih Bukhari, Chapter: Loans, Payment of Loans, Freezing of Property and Bankruptcy

The Prophet (SAW) said, "Allah has forbidden for you, (1) to be undutiful to your mothers, (2) to bury your daughters alive, (3) to not to pay the rights of the others (e.g. charity, etc.) and (4) to beg of men (begging). And Allah has hated for you (1) Qil and Qal (useless talk, or that you talk too much about others), (2) to ask too many questions, (in disputed religious matters) and (3) to waste the wealth (by extravagance with lack of wisdom and thinking).
