Sayyidah Aishah (may Allah be pleased with her) said: I used to apply perfume to the Messenger of Allah (peace and blessings be upon him), both for his coming out of ihram and for his entering ihram. Salim said: The Sunnah of the Prophet (peace and blessings be upon him) is more deserving to be followed.
