The mysteries of the human self is an ambiguous world that only Allah The Exalted knows the essence of. This self varies from one person to another, and even a single human self is in itself subjected to changes from time to time. It is also influenced by new things, whether feelings or opinions, which change its state. All this is contingent on the dealings of the people surrounding it and the circumstances of time and place.

　　Life around people is changeable. Accordingly, people's reactions change and they give different responses to different problems, and this is natural in this life which is constantly changing and in perpetual motion. Allah The Exalted, the Creator of such selves, is the only One who is fully acquainted with the nature of their internal changes. No one is capable of understanding their nature but He, who Says (what means):

• {And know that Allah knows what is within yourselves, so beware of Him.} [Quran 2:235]
• {And conceal your speech or publicize it; indeed, He Is Knowing of that within the breasts. Does He Who Created not Know, while He is The Subtle, The Acquainted?} [Quran 67:13-14]

• {And Allah wants to lighten for you [your difficulties]; and mankind was created weak.} [Quran 4:28]
