Is it permissible to help a girl who works in a nightclub establish a small business, so that she may become chaste and earn lawful money, with a guarantee that she will not return to what she was doing?

Helping a needy woman to abandon unlawful earning is a righteous deed that combines assisting the needy and helping to forsake sins. The hadith of Abu Hurairah indicates the acceptance of charity given to a thief, an adulteress, and a rich person. However, one must be cautious of acquaintances forming between men and unrelated women due to the temptation involved. If marriage to her is possible, it is preferable.
