Question: What is the ruling regarding applying perfume on the ihraam before making the intention and the talbiyah?
Response: It is not befitting to apply perfume on the ihraam, rather, the Sunnah is to apply the perfume on the body such as the head, the beard and the armpits, and other such places. As for the ihraam, then do not apply perfume on them for that which the Prophet (sal-Allaahu ‘alayhi wa sallam) said:
«Do not wear clothing which has been ‘touched’ by az-za’faraan or al-wars (i.e. types of perfume)».
So, the Sunnah is to apply perfume on the body only and as for the ihraam, then perfume is not to be applied on it. And if it has been, then it is not to be worn until it is washed or changed [for a cleaner one].
