The World Federation One Stop Fiqh

Ruling 2076

If something that can be used in a lawful manner is sold so that it is used in an unlawful way – for example, a person sells grapes so that wine can be produced from them – then, irrespective of whether it was decided to sell that thing for the unlawful use at the time of the transaction or before it, if the transaction takes place on the basis of the unlawful use, it is unlawful. However, if a person does not sell it for that reason but knows that the buyer will produce wine from the grapes, there is no problem with the transaction.
