Continue but in a good way that don’t lead others mocking on our religion. If you laugh during her class, this is what you get in return. Respect others and you will be respected.

Our teacher was talking about fundraising by selling roses which students can give to the opposite sex. I said to my Arab friends, “Hada ma halal.” When she noticed us laughing, she asked me what I had said. I told her. She started mocking me and all the kuffar laughed. Have I done the correct thing or should I stop talking so much about Islam and decrease my dawah?
