Assalāmu ‘alaykum wa rahmatullāhi Wabarakath,
This is a video I came across, called, 'Whisperings from Shaytan - Don't wear Hijab properly'.
Apart from me finding it a little funny for some reason, it does actually have a very important message to give. There are a large number of Women who although may don Hijab, don't do it properly or don't do it for the right reasons. A lot of Women, especially girls tend to fall into the entrapments of Shaytan when it comes to wearing Hijab.
On a side note, I'd like to add that a lot of girls who first delve into the world of Hijab are hesitant about it, especially if they don't have a strong backing or support and therefore the Hijab starts out as a half-hijab or the small ones. We shouldn't be judgmental of these Women and insha'allah, make dua that they start wearing Hijab properly.
