Do you know a sign that your piety is fake? This is something that is extremely important for us all to be aware of!
When you get close to Allah, one of the signs that you are close to him is your heart becomes soft. You become soft with other human beings.
The way you talk to them shows respect, the way you reach out to them shows concern for them. In a beautiful way that is a sign of the mercy of Allah. It shows you are close to Allah.
If you think you are pious and have an attitude with no gratitude it is fake piety.
