Is it permissible to use flour moistened with water to play with, for the purpose of training mentally disabled individuals to move their fingers, and then dispose of it?

There is no harm in making shapes out of flour or dough for non-living things, in order to train mentally disabled individuals to move their fingers. It is preferable to benefit from the dough after training, even if by drying it and feeding it to an animal to preserve the bounty. If it is not possible to benefit from it, then there is no harm in discarding it. Some scholars have issued fatwas permitting the use of some foodstuffs in shampoo and similar washing products. The scholars of the Permanent Committee for Issuing Fatwas have issued a fatwa permitting washing with shampoo mixed with eggs or lemon.
