Is the sale by touching and throwing restricted to the blind only?

Question:
He says: Honorable Shaykh, may Allah grant you success, is the sale by touching and throwing restricted to the blind only, or does it also include the sighted?

Answer:
This is among the sales that are prohibited. The Messenger (peace and blessings be upon him) prohibited the sale by touching and throwing, and the sale by throwing a pebble. Touching is when he says, "Any garment I touch is yours for such-and-such." This is unknown; one does not know what he will touch. This is unknown. And the sale by throwing is when he says, "Any garment I throw at you and cast toward you is yours for such-and-such." I will enter and take the leftovers and throw them at you; any garment I throw at you is yours for such-and-such. This is not permissible.
As for the sale by throwing a pebble, it is what we mentioned: he says, "Take this pebble and throw it; whatever it lands on is yours for such-and-such," or "whatever place on the ground it lands in, I sell it to you for such-and-such." This is not permissible because it is unknown. Yes.
