Muslim women wearing Hijab in the presence of non-Muslim women

Q 1: Is it obligatory for a Muslim woman to wear Hijab (veil) in the presence of non-Muslim women or should they be treated like Muslim women?

(Part No. 17; Page No. 287)  A: There are two views in this regard and the soundest view is that it is not obligatory for her to wear Hijab the presence of non-Muslim women. This was not reported from the Prophet's wives (peace be upon him) or any other female Sahabah (Companions of the Prophet) when they gathered with Jewish and idolater women in Al-Madinah. If this had happened, it would have been reported, because less important events were reported. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
