It is narrated by A’ishah who stated, “I applied sweet flag/calamus upon the Messenger of Allah ﷺ with my hand during the Farewell Hajj at the time of leaving and entering into the state of Ihram.”
(Al Bukhari)
The word Zarirah is used in the Hadith which is explained in the commentaries of Hadith to mean a combination of perfumes and also a name for a specific type of fragrance that was well known in the land of Hijaz and other places. Al Imam An Nawawi and other scholars stated that it is a type of fragrant stick that is found in India. Based upon this it is understood to refer to sweet flag.
