Benefit: O Muslimāt! Don't Mock Your Sisters!
In the Name of Allāh, the Ever Merciful, the Bestower of Mercy
O you who believe! Let not a group ridicule at another group, it may be that the latter is better than the former. Nor let (some) women scoff at other women, it may be that the latter is better than the former, nor defame one another, nor insult one another by nicknames. How bad is it, to insult one's brother after having Faith. And whosoever does not repent, then such are indeed Ẓālimūn. (49/11)
Our brother, Abū al-ʿAbbās Mūsá Richardson while mentioning the explanation of the aforementioned verse, discusses the actions done by some sisters in the way the deal with others who don’t wear the niqāb; whether they don’t wear it following a specific school of thought, position of a scholar or general lack of study on the issue. This segment also discusses the affiliation founded upon garments (i.e. groups, forums, mailing lists, etc, specific for those who adorn the garment of niqāb) Sisters! You are bound together by an ʿaqīdah and a manhaj, not a veil! This issue is further exasperated considering the majority of ʿulamāʾ historically, have not held the niqāb to be obligatory but rather recommended, so perhaps caution and care is needed when giving daʿwah to one another.
