Answered by Shaykh Amjad Rasheed
If I use scent that has alcohol in it, does it nullify my wudu? Can I pray with this scent on my body?
Applying scent to the body does not nullify wudu, even if you know that there is filth (najasah) in it.
As for the ruling of praying with it, if the person praying is certain that the scent that is on him indeed has filthy alcohol in it, his prayer is not valid.
But if it is not filthy, or if he has doubt about it, then his prayer is valid. So let the questioner go to specialists who know about the types of alcohol [s. so he may find out if it is an intoxicating kind] and it is best for him to avoid it altogether, and nothing is equal to safety.
