If a الحاج in the state of الإحرام accidentally uses perfume — whether by forgetfulness, ignorance, or being applied by someone else without their knowledge — the majority of scholars hold that no فدية (ransom/penalty) is required, provided the الحاج removes or washes off the fragrance immediately upon realizing the mistake. This ruling is based on القرآنic principle that Allah does not hold people accountable for genuine mistakes and forgetfulness, and the hadith in which النبي (صلى الله عليه وسلم) said: 'My ummah has been forgiven for mistakes, forgetfulness, and what they are coerced into.'
الشيخ ابن عثيمين explicitly addressed this scenario, ruling that if a person in الإحرام applies perfume out of forgetfulness or ignorance of the prohibition, they must wash it off as soon as they remember or learn of the ruling, and no فدية is due. He distinguished between three cases: (1) intentional use with knowledge — فدية required; (2) intentional use without knowledge of the prohibition — no فدية عند the stronger opinion; (3) accidental or forgetful use — no فدية. In all cases, the perfume must be washed off immediately.
الشيخ ابن باز similarly ruled that accidental violations of الإحرام restrictions do not incur penalties, whether the violation involves perfume, covering the head, or other prohibitions. He emphasized that the الحاج must act to correct the situation as soon as they become aware. If the الحاج deliberately delays removing the perfume after becoming aware, then فدية becomes due for the period of deliberate continuation.
