Al Batin - The Hidden
Al Batin is the One who is Hidden. He is hidden in each one of His creations for His beauty and perfection of creativity. Al Batin also has a meaning of being innermost. It is considered as the opposite of Ad Dahir. (The Dominant).
As we know the ظاهر is derived from ظ ه ر which is the back. It is on the outer side of the body. On the other hand, باطن is derived from ب ط ن which is a word in Arabic for the belly.
The belly is part of the body that carries the internal organs and it is the hidden foundation for nourishment, strength, and growth for the whole body.
Likewise, the innermost hidden source of strength, motivation, and support that never leaves us alone is the presence of our Rab, which is hidden yet the most powerful & reliable for all who rely upon Him.
ALLAH knows us the innermost. He is the nearest one to us even before ourselves.
He knows us when we were not born and we were in the secure body of our mothers and also when we were babies and totally dependent. He knows our needs, our characters, and our deeper hidden traits which no one else knows. He is our loving Rab - Al Batin.
ALLAH Al Batin is hidden as He cannot be seen in a physical appearance. Glory be to Him, He is seen in His creation through His actions, decisions, and the signs, He is in power and visible despite being hidden.
So whoever thinks and takes time to know the systems of the earth and the skies and what all is in them, the system of our lives and deaths will know the knowledge of reality. This knowledge tells us that all of these great creations including us have a Creator and Sustainer.
Human share in this name is the real focus of our lives and that is the day we will meet and finally see our Rab. Many ayaat and hadith prove that believers will see their Rab on the Day of Qiyamah and onwards in Jannah. So that final success will qualify us to meet our Rab. Each day in this life we may make our best efforts to prove ourselves successful to see our Rab and able to see Him in a better position we can achieve by our good works in this life.
