Does perfume applied to the body and clothes conflict with purity (tahara) and prayer (salat)? And if it is impure, how can a woman adorn herself and wear perfume for her husband?

If the perfume is free of alcohol, it does not affect ritual purity (tahara) or prayer (salat), though it is forbidden for a woman to leave her house wearing perfume. However, if the perfume contains alcohol, it is preferable to avoid it in prayer and other situations.
