What is the meaning of the Hadith that prohibits wearing clothes dyed with saffron, and what is the meaning of the word "muza'far" (مُزَعْفَر)?

The questioner might be referring to the Hadith in Bukhari from Ibn Umar (may Allah be pleased with them both), that the Prophet ﷺ forbade a pilgrim in ihram from wearing clothes dyed with wars (safflower) or saffron. The meaning of this is that it is forbidden for a pilgrim in ihram—whether male or female—to wear anything containing perfume. "Muz'afar" means dyed with saffron, which is a perfume, and for this reason, it is forbidden for a pilgrim in ihram to wear it.
