Dear and respected Brother Shamim, if one were to believe and continue to look at the text of AlKitab (the bound book of eternal principles), as only meant for Arabia. This kind of understanding will make sense. But, if one were to sit back and think Quran as eternal book of principles and look at it; as the creator addressing all creation and at all times, meaning transending limits of person, time and space. Then, the linguistic understanding, I am presenting, would start making sense. Please look at it from this point of view. I know a person of your ablity already knows, what I just said above. Hence, it is just like an attempt to show light to a lamp, from an ignorant like myself.
Surah 94: 1 أَلَمْ نَشْرَحْ لَكَ صَدْرَكَ
Haven’t we/I laid open, revealed and disclosed all to you? You turned away, shunned and forsook it, and distanced yourself, considering it weak or incorrect.
With lots of love and peace for all.
