Sayyidah Umm Salamah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), relates: We would be with the Prophet (peace and blessings be upon him) in the state of ihram, and when a rider passed by us, one of us would let her cloth hang down over her face from above her head. And sometimes she said: from above the head-covering.
