All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Undoubtedly, it is better for a woman to stay at home; this reflects piety on her part. It is her husband who is required to spend on his wife and children. It is blameworthy if the husband is able to work and he does not do so, and he could even be sinful. The Prophet said: “It is enough a sin for a person not to provide means of sustenance to those whom he is obliged to support.” [Muslim].
If a woman takes the burden of spending on herself, the children [and her husband], or participates in spending and fulfilling the house requirements, then she is rewarded for doing so, Allaah willing, and she is not sinful. She is to be thanked and praised for what she does especially if her husband is unable to work, or that his earnings are not enough, or that he experiences financial difficulties and the like. In this case, she will get a great reward from Allaah for her expenditures as this is being kind to her husband and strengthens the marital relationship between them; which is something religiously urged. This is what the wives of the righteous predecessors used to do. For instance Khadeedjah used to help her husband who was the Prophet with all her money, and she was not saving any, and he was grateful to her for doing so.
Similarly, you will be rewarded, Allaah willing, for buying books for your husband and helping him in seeking religious knowledge, and we ask Allaah to enable you to do good and help you to perform more righteous deeds.
