The Questioner: Is wiping [valid] over any type of ʿimāmah (turban), and as well as the ghutrah?
Shaykh Muqbil: The ghutrah, in itself, is called a khimārm, like the one the brothers take and leave it [hanging] here, and such, it is called a khimār. And the Prophet ﷺ wiped over the ʿimāmah, which is the one that is wrapped (liyy), and [also] over the khimār. Thus, there is no harm in wiping over the ʿimāmah, and wiping over the khimār.
The Questioner: No matter what the shape of the ʿimāmah [is]?
Shaykh Muqbil: No matter what the shape of the ʿimāmah is, Naam.
