Wiping over Hijab during Wudu
What is the ruling of wiping over my hijab (head cover for women) instead of wiping over my head in wudu (ablution)?
In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright.
It is permissible for a woman to wipe over her hijab (head cover) in the case of necessity, such as when it is very cold, or it is difficult to take off her hijab and put it back on.
In a fatwa of Sheikh Ibn `Uthaimeen in which he said, “The well-known view in the school of Imam Ahmad is that a woman may wipe over her khimar (a dress covering the head and the upper part of the body) if it goes under her chin, because it was narrated that some of the wives of the Companions (may Allah be pleased with them) did that.
Whatever the case, if there is some difficulty, either because the weather is cold or because it is difficult to take it off and put it on again, then there is nothing wrong with wiping in such cases, otherwise it is better not to do that. (Fatawa At-Taharah)
