Wa alaikum assalam brother Munir,
I have discussed this in at least a couple of different contexts; One in an article discussing whether believers have to pray in Arabic
[1] and the other, in an article relating to testimony
[2].
In the latter article, I wrote:
EACH ONE OF US HAS ALREADY TESTIFIED TO THE TRUTH OF ONE GOD007:172
"And when your Lord brought forth from the children of Adam, from their loins, their descendants, and made them bear witness (Arabic: ashhadahum) against their own souls: Am I not your Lord? They said: Yes! we bear witness (Arabic: Shahidna). Less you should say on the Day of Resurrection: Surely we were heedless of this" This 'testimony' taken from all souls at its spiritual birth cements the concept that
perception of the existence of a supreme power (God) is innately instilled as part of human nature (Arabic: Fitrat). It is this very instinctive cognitive ability that is either corrupted from the truth by human volition, or grows in accordance with truth.
091:007-10
"And a soul and Him Who perfected / proportioned it. And inspired it (with conscience of) what is wrong for it and (what is) right for it. He is indeed successful who causes it to grow (purifies it), and he is indeed a failure who corrupts it (buries it)"I hope that helps, God willing
Joseph
