What is the ruling on the niqab during tawaf?

Question:
The questioner says: We request clarification on the issue of the niqab for women, and why a woman’s face is uncovered during tawaf?

Answer:
Who said that a woman’s face is uncovered during tawaf? No, that is a mistake. A woman’s face is not uncovered; a woman’s face is covered in the presence of men, both during tawaf and otherwise. However, it is covered without the niqab and without the burqu’ (face veil). Rather, she covers it with the khimar (head covering) or the garment she is wearing, draping its edge over her face, and she does not uncover her face during tawaf. As for the niqab, according to custom, if it is the custom of the country that they wear the niqab, she wears the niqab. But it is not the niqab known today, from which much of the face is visible. That is not the niqab. The niqab is that which has no opening except the size of the eye; the opening is only the size of the eye.
She is visible through it. As for the niqab from which something of the face emerges beyond the eyes, that is not the known niqab. Yes.
