The difference in the ruling on a woman covering her face when she is in Ihram and when she is not

Q 1: What is the difference in the legal ruling on a woman covering her face when she is in Ihram (ritual state for Hajj or `Umrah) and when she is not? (Part No. 11; Page No. 317

A: A woman should cover her face in the presence of non-Mahram persons (not a spouse or a permanently unmarriageable relative), whether she is in Ihram or not. But in the state of Ihram, she is not required to cover her face with a veil or a knitted cloth specified for covering the face; rather, she may conceal it with something else.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
