Prostrating on the edge of the shemagh on top of the mosque's carpets

Question:
The questioner asks: Is it permissible for the one praying to place the end of his shemagh to prostrate on it on top of the mosque carpet?

Answer:
If he has a need, if he needs to place his shemagh to prostrate on it because the mosque carpet has dust on it or has a bad smell, then there is no harm in that. So if this is for a need, there is no harm, such as if the place is hot, or has thorns, or has pebbles, or has a smell, or has dust, and he places the end of his shemagh and prostrates on it, there is no harm. Yes.
