When your parents start seeing your hijab as a danger to your safety or your economical well-being, we need to go back to the source.
Your safety, your rizq, your income and provisions in this life are within the Hands of Allah. Your parents may worry about how an interviewer feels about your faith, but the ultimate decision on your hire-ability isn’t coming from HR. It’s coming from Allah.
Your parents may worry that hijab makes you a target, and given that Muslim women are the most conspicuous targets of Islamophobia, you can understand where their fear is coming from. Your safety though, comes from another place. Allah is your Protector, your Sustainer, and your Guide.
