Is the hijab obligatory for women at all times and in all places, and is its abandonment a sin? What is the sin of a husband whose wife he commands to wear the hijab but she only obeys him in the markets? What is his duty towards her?

There are two meanings for hijab: The first is covering the entire body except for the face and hands. This is obligatory by scholarly consensus, and the sin of the wife intensifies if her husband commands her to wear it and she disobeys him. The husband must obligate his wife to wear it. The second is covering the face and hands. This is a point of contention among jurists, and the preponderant opinion according to us is its obligation, but the matter is less stringent than the former.
