What is the ruling on performing tawaf wearing only one garment that does not cover the 'awrah?

The questioner : Some people in ihram enter the state of ihram wearing only one garment that does not complete their covering. Is this forbidden, or does it invalidate the 'Umrah? What is the ruling on this?

Another questioner : I think she is saying that she wears nothing but a belt.

The Shaykh : I mean, some Muslims say that if the garment covers his 'awrah, then half of his worship is valid. But if the garment does not cover his 'awrah, then his worship is not valid. This is because one of the conditions of tawaf is covering the 'awrah, as stated in the authentic hadith: . So if the garment covers the 'awrah, then his worship is valid with that. However, it is better to enter ihram wearing an izar and a rida'.
