Narrated by Ibn 'Abbas
The Prophet said: "I was shown the Hell-fire and that the majority of its dwellers were women who were ungrateful." It was asked, "Do they disbelieve in Allah?" (or are they ungrateful to Allah?) He replied, "They are ungrateful to their husbands and are ungrateful for the favors and the good (charitable deeds) done to them. If you have always been good (benevolent) to one of them and then she sees something in you (not of her liking), she will say, 'I have never received any good from you."

At Ar-Rabadha I met Abu Dhar who was wearing a cloak, and his slave, too, was wearing a similar one. I asked about the reason for it. He replied, "I abused a person by calling his mother with bad names." The Prophet said to me, 'O Abu Dhar! Did you abuse him by calling his mother with bad names You still have some characteristics of ignorance. Your slaves are your brothers and Allah has put them under your command. So whoever has a brother under his command should feed him of what he eats and dress him of what he wears. Do not ask them (slaves) to do things beyond their capacity (power) and if you do so, then help them.' "
