The Prophet (Peace be upon Him) said, “Allaah 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 Allaah has hated for you

1. vain, useless talk, or that you talk too much about others,
2. to ask too many questions, (in disputed religious matters),
3. and to waste the wealth (by extravagance).”
