Istifta 15436 — Prayer - Clothing
Even though some manufacturers write on their products that they have been made of natural silk, we doubt such a claim because of the goods very low price. Is it permissible for us to wear such an item and say salãt in it?
Answer
With doubt [whether the silk is pure], it is permissible to wear and say salãt in it.
