I’m part of a committee in a society that deals with the spreading of the good of Islam. In that committee, almost every day, we are advised to make our intentions clear and ensure that it is right.
A good example would be the intention to enrol into university. If your intention is to graduate with a degree and learn as much as possible in university, that is a right intention whereas, if your intention is to party and have fun in university, that might not be right and thus, you might suffer the consequences.
Thus, I made it a habit to ensure that my intention of doing something is clear and proper and you should too.
