This is among the innovations that has no basis. We have been commanded to follow the Messenger of Allaah (sallal-laahu-alayhi-wasallam), (so) follow and do not innovate. ”Indeed in the Messenger of Allah (Muhammad) you have a good example to follow.” [Ahzaab: ayah: 21]. We neither know of the Messenger touching the kabah’s cloth nor his companions, and had it been a good thing, they would have preceded us in it. Therefore, touching the kabah’s cloth or the two walls of the Messenger’s compartment or the netting on it, then all of this is an innovation that has no basis in the Islamic legislation.
