Go and learn about what the Muslims did when they conquered Andalusia. It was a great civilization to the point that the King of Britain at that time asked the Islamic University to accept his daughter there, and when the Muslims began to depart from the religion, God punished them, so the enemies gathered against the Muslims and defeated them, and It is worth noting that when Christians tortured Muslims, they had an interesting way to reveal the Muslim person to the Christian person. They used to enter the toilets. If they found it clean, he was a Muslim, and if it was dirty, he was a Christian or a Jew.
