Explanation of the Jilbab for the Muslim Woman.

The Shaykh : on their laps. It is known in the Arabic language that the khimar is the head covering, as the Prophet (peace and blessings be upon him) indicated in his saying: So the khimar is the head covering. If Allah (Mighty and Majestic) commands women to place the khimar on their heads and forbids them to strike with their feet so that what they hide of their adornment may be known, and He commanded the jilbab before that, this means that the jilbab is placed over the khimar that is on the head. It is not sufficient to have a khimar over a qamis over a dir'. No, the khimar is placed on the head, and over the head is the jilbab. These are two matters explicitly mentioned in the Qur'an, so it is necessary to combine them. This is also from the perspective of sadd al-dhara'i' (blocking the means to harm), because the jilbab may open, and the khimar serves as the backup. This is the answer to what you asked.
