But if she hires it out to a woman who adorns herself with it in order to commit sexual immorality, this is too grave a matter even to ask about.

Allah Most High says:

“Cooperate in righteousness and piety, but do not cooperate in sin and aggression.”

It is not permissible to help anyone commit sexual immorality or any other sin, whether by providing jewellery, clothing, accommodation, a riding animal, or anything else, whether for hire or otherwise. And Allah knows best.

He—may Allah have mercy on him—was asked:

Candle sellers hire out candles, weighing them before handing them over, then weighing them again upon their return and charging for the loss in weight. Is this disliked? If a candle breaks, is the person who hired it liable or not?

He answered:

If someone gives candles to another person to burn, saying, “For every ūqiyya (a unit of weight) consumed, the charge is such-and-such,” this is permissible. It does not fall under lease contracts or binding sales, since a binding sale requires the goods being sold to be known. Rather, it is a revocable exchange, not a binding one.

This is like saying, “Live in this house for one dirham a day,” without specifying a term. This is permissible according to the stronger of the two scholarly opinions. Thus, this case involving tangible property is analogous to that case involving the use of property. It constitutes permission to consume the property
