The Ruling on Obsessive Doubts in Ritual Purity

Question:
Your Excellency the Shaykh, some people have many obsessive doubts and are prone to excessive doubt in this matter, the matter of ritual purity. So when he comes to a place, or even sometimes in a mosque, he says, “This mat seems to have something on it,” “This carpet seems to have something on it,” “This spot seems to have something on it,” and he invalidates his prayer and the prayer of the people.

Answer:
This is obsessive doubt. This is considered to be from those who suffer from obsessive doubts, or from the ignorant, or from those who are extreme in their practice. There are those who are extreme due to their lack of jurisprudence and knowledge. The default is purity, and praise be to Allah, in the mats, in the mosques, in the earth, and in the default state. Purity is the default unless you know that there is ritual impurity on it, in which case you remove it. Yes.
