Is it haram to pray with a face mask on?

Answer:

It is perfectly acceptable to pray while wearing personal protective equipment (PPE) that safeguards against viruses, even if it fully covers the face and body. The key requirement is that the worshipper must be able to place their nose and forehead on the ground during prostration. This is supported by a narration from al-Bukhaari (812) and Muslim (490) as reported by Ibn.
