Can I make the hat of Israelis for their religion?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

It is not permissible to make this Jewish hat as long as it is one of the slogans of the Jews and it is peculiar to them and no one else uses it. If one makes these hats, he approves of their false beliefs. Allah Says (what means): {Help you one another in virtue, righteousness and piety but do not help one another in sin and transgression.} [Quran 5:2]

Therefore, you must seek lawful sustenance and fear Allah, and Allah will provide you from sources you never could imagine. This is the promise of Allah.

Allah knows best.
