Is it permissible to do masah over hijab when performing wudhu because sometimes women are in market, where it is so difficult to pen the hijab?
بسم الله الرحمن الرحيم
(Fatwa: 159/102/SD=2/1439)
No, it is not lawful to do masah over Hijab. The fardh of masah shall not be fulfilled. She should do masah behind some partition.
Allah knows Best!
