The Ruling on Praying in Shoes
Machine translationRead the Arabic original
Question:
Is it permissible to pray in shoes?
Answer:
Praying in sandals is a recommended practice (sunnah) if they are pure and free from impurity. However, if the mosques are carpeted and clean, as is the current custom, do not enter them wearing sandals, because this will defile them. This defiles the mosques. In the past, they were earthen, and sandals did not affect them or leave a mark on them. So it was seen with them. But now the situation has changed. Yes.
