ANSWER:

One should be proud of his religion and say it for the sake of Allah and not for them. There is no sin in not saying it though.

QUESTION: Is it ok if we dont say inshaAllah to non muslims for future events. Like sometimes int eh whatsapp group we have to tell that we will not be coming tomorrow. I fear saying InshaAllah because they will probably think why am I including religion over everywhere. Even for my prefect application, I dont think I said clearly, “I will” to anything.
