So there are mainly two aspects of this situation
- There is some supernatural force which is following you
- There is a person who is following you either can be your friend who is about to surprise you from behind or someone else (Which will be completely not in our favor)
So keeping these situations in mind I will just walk confidently and will increase my speed of walking to reach my destination as soon as possible and will keep reciting the verses of Quran so that the Almighty keep me safe from any bad happening.
