It is very easy not to commit a haram and to observe the rules of Islam. It seems difficult to the sick-hearted. Yes, there are many jobs that are easy for healthy people.

Even if such people say that they believe, it is not a real confirmation. It is a confirmation through words. A symptom that indicates the existence of a real confirmation, true iman in the heart, is to feel it easy to follow the path of the Ahkam Islamiya.
