Well said brother. I totally agree to you that hijabis are presenting a religion of Allah (swt). They are not trying to please non-Muslims, but present to them a practical example of a good Muslim, so non Muslims find it easy to understand and follow Islam. I said hijabis should be careful because any misunderstanding about their intentions might lead to a bad impression of Islam infront of non-Muslims.
Once on a flight the meal served to people contained pork. The flight crew knew that Muslims don’t eat pork, so they served non-pork meal to women with hijab and men with beard. Later a Muslim family came to know about it so they protested. The crew apologised to them and told them that they didn’t “look” Muslims so they mistakenly served the pork meal to the family. Yes, what we wear does to some extent indicate our identity to non-Muslims, that is why we need to be careful and not make a mistake that leads to misunderstanding about Islam.
