Ask them (O Muhammad) of the township that was by the sea, how they did break the Sabbath, how their big fish came unto them visibly upon their Sabbath day and on a day when they did not keep Sabbath came they not unto them. Thus did We try them for that they were evil-livers.

Chapter: The reward of the lady who gives in charity, from her husband’s house
Narrate Aisha:
The Prophet (ﷺ) said, "If a woman gives in charity from her husband's house .." The Prophet (p.b.u.h) also said, "If a lady gives meals (in charity) from her husband's house without spoiling her husband's property, she will get a reward and her husband will also get a reward likewise. The husband will get a reward because of his earnings and the woman because of her spending."
