So a person could show generosity, there is not one, but thousands of methods. Muslim woman must also join the shares to charity and be generous.
Woman who received an inheritance, gifts or earned by honest labor, and all the material means which reached sizes nisab must pay Zakat and Sadaqah Fitr, to make a sacrifice, and if she has enough power and capabilities, she may go for Hajj.
As regards other types of righteous works, this woman has complete freedom of choice. Her personal means she can spend on her own discretion and while it is not necessary to ask permission of the spouse. If her husband is poor, it is desirable that a wealthy woman made a donation in favour of her husband and spent her money on her children, relatives or neighbors.
As for the woman who has no personal property, and who is a dependent spouse, she is solely responsible for the safety of the property of her husband and the contents of the inner peace of the house (apartment) in order.
To such a woman had the right to make expenses, she must ask permission from her husband, but permission must not be of a specific, it must be a generic.
All Muslims men recommended to give their spouses a general permission. For example, a woman could quietly help when neighbors asked for some bread or milk or something to borrow, to treat the guests and give food to the poor neighbors.
General permission given in accordance with local practice. And even if the financial situation is poor, though anyone can somehow help neighbors or relatives. And so in that respect no one should show stinginess.
Specific permission given for other types of benefits, and therefore, no one woman without the permission of a husband has no right to perform them. The only exception is the case, if the husband said to her, “Do as you desire”.
Remuneration for the donation that a woman or a servant made of husband's property or the owner, recorded as the one who made them, and the one who earned it.
On this occasion, the Messenger of Allah (peace be upon him) said:
“If a woman makes a donation of the property of the husband or distributes food without going beyond reason, it is written benefit. Savab written for her husband, who earned it. So it is with the good deeds of employees. The one, who deserved Savab, does not detract from the merits of other people”.
