What is the ruling on part of a woman's forearm being uncovered when raising her hands in prayer, and is it obligatory to cover what appears from the extension of the sleeve opening when looking through it, and does Ibn Hajar's statement apply to this situation: "If the sleeve is wide and let down in such a way that her awrah is seen through it, the prayer is not valid, as there is no difficulty in covering it, and also, this is a view from the side, which is harmful absolutely"?

A woman must cover her entire body during prayer, except for her face and hands. It is a precautionary measure to extend the sleeves so that the wrist and the area above it are not uncovered. Uncovering the forearm due to wide sleeves invalidates the prayer. Scholars differed on the ruling concerning the uncovering of the awrah during prayer: The relied-upon view among the Hanbalis is that if it is slight and unintentional, the prayer is valid. However, if it is extensive, the prayer is invalidated according to the general consensus of scholars. And if it is slight but intentional, the prayer is invalidated.
