The question of applying perfume before entering الإحرام is one where the four schools of jurisprudence differ based on their interpretation of the hadith evidence. The majority position, held by the Shafi'i and Hanbali schools, is that it is السنة (مستحب) to apply perfume to the body — but not to the الإحرام garments — before making the intention for الإحرام at the الميقات. This is directly supported by the practice of النبي Muhammad (صلى الله عليه وسلم), as reported by his wife Aisha (رضي الله عن her).
Aisha narrated that she used to perfume the Messenger of Allah (صلى الله عليه وسلم) before he entered الإحرام, and she could see the traces of musk glistening on his scalp and in his hair parting even after he had assumed الإحرام. According to scholars who hold this position, the prohibition of perfume during الإحرام applies to new application after entering the state of الإحرام, not to residual fragrance from before. The perfume should be applied to the body (head, beard, skin) but should be avoided on the الإحرام garments themselves.
The Hanafi and Maliki schools take a more cautious view. They consider it مكروه (makruh) to apply perfume immediately before الإحرام if its scent will remain perceptible after entering the sacred state. Their reasoning is based on the hadith prohibiting the muhrim from using perfume, and they view lingering fragrance as tantamount to ongoing use. Imam Malik specifically noted that using perfume that lingers is problematic, though no فدية is required since the application occurred before الإحرام. Despite this difference, all scholars agree that there is no sin or penalty for residual fragrance that naturally fades.
