How does women who is doing Umrah (who uncovers her face because of Umrah) cover herself when the men pass by her ?
The women who is doing Umrah, if the men pass by her or she pass by the men then it is Wajib (compulsory) to cover her face, for the Hadeeth of Umm Salamah Radiallahu Anha, that she said we were with Messenger of Allah Sallallahu alaihi wa sallam and if the riding men pass by us then we covered or lowered down (veil) upon our faces.
[Narration was found in Sunan Al Kubra Lil Baihaqi – 9317]
So she cover’s her face. And it is not allowed for the women who does Umrah to wear niqab (a cloth wrapped over face to cover face) and it allowed her to lower down the Khimar (the cloth covered over the head) and cover her face with that. And what has come in some books of Fiqh that it is not allowed to make the Khimar touch the face, there is no proof for that. And the proof is that she covers her face for the hadeeth of Umm salamah mentioned above and also similar narration came from our mother Aaisah radiallahu anhu. And the people of knowledge rahimahullah have ruled with this ruling like our Shaykh Al Imam Muqbil Al Wadiee.
