Sell dates and yeast

A: It is not permissible to sell grapes to those who use them in making Khamr, and it is similarly impermissible to pick or prepare them for those who make Khamr. Allah (Exalted be He) says: ...but do not help one another in sin and transgression. The Prophet (peace be upon him) cursed Khamr, its consumer, its presser, the one for whom it is pressed, its seller, its buyer, the one who benefits from its price, its carrier, and the one to whom it is carried, for they all help one another in sin and transgression.
