All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
It seems that the questioner means the Hadeeth narrated on the authority of Ibn ‘Umar in which he said: "The Prophet, sallallaahu ‘alayhi wa sallam, forbade the Muhrim (a person who is in a state of Ihraam) to wear clothes dyed with Wars or saffron." [Al-Bukhari and others]
Briefly, the Hadeeth means that a person, man or woman, who is in a state of Ihraam to perform either Hajj or ‘Umrah is forbidden to wear perfumed clothes. Saffron and Wars are two types of perfume and therefore a person in a state of Ihraam is forbidden to wear clothes dyed with them.
