Sahih Bukhari - Hadith No. 591
Narrated by Al-Mughira bin Shu'ba: The Prophet 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) vain, 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).
This is a reminder to me before anyone else. May Allah preserve from ever falling into any of these categories.
