The word “fear” always associates with something negative and which is hardly appreciated. But when the fear is only for Allah the Almighty and the Creator of this universe, then it can change a human being. The fear of Allah can lead to freedom of the soul from all kinds of earthly restriction and inspire a human being to worship only Allah. The fear of Allah is the core aspect of Islam and those who do not have this are not considered as Muslim.
The fear of Allah has profound effect in every aspect of life. Those who possess the fear always follow the path showed by Holy Quran and the Prophet Hazrat Muhammad (SM). The fear of Allah purifies a Muslim. Those who have fear in heart they are supposed to follow every order of Allah. In this case the most important aspect is that a Muslim has to believe that Allah is one and no one can be compared to Allah.
This is been reinforced in Quran for a number of times. Apart from this, the fear of Allah will be reflected by each and every work of a Muslim which will lead them to the ultimate goal- Heaven.
