It does not suffice to say I am a believer, nor does it suffice for me to say that I fear Allah (swt). The proof of the fearing of the position of Allah (swt) requires a proof and its proof is (Preventing the soul from its (unlawful) desires).

Therefore, if you do not prevent yourself from following its unlawful desires, you actually do not possess fear of Allah (swt). This is because, the self is naturally inclined to follow its desires and the Hellfire is surrounded by all that is desired.
