Towards understanding few verses of Glorious Quran

Towards understanding few verses of Glorious Quran.

The Revelation of ALLAH(the Quran)is not an occasion of distress, but is a Gift of Mercy from ALLAH Most Gracious.
ALLAH's revelation is not an occasion for man's distress; it is a Message to show that ALLAH the All-Knowing sits on the throne of Mercy and guides all affairs. There is no god but He; to Him belong all the Most Beautiful Names.
Surah Ta Ha

Chapter 20:1-8
Bismillah Ar Rahman Ar Raheem
"Ta Ha. We have not sent down the Quran to thee to be(an occasion)for thy distress,but only as an admonition to those who fear (ALLAH)- a revelation from Him Who created the earth and the heavens on high. "
[Surah Ta Ha 20:1-4]

ALLAH's revelation may cause some human troubles for two reasons:
(1) it checks man's selfishness and narrowness of view, and
(2) it annoys the wicked and causes them to jeer and persecute.
These are mere incidental things,due to man's own shortcomings. As far as the trouble is concerned, the Revelation is meant to give a warning, so that persecutors may be reclaimed, (and of course for men of faith it is comfort and consolation,though that point does not arise in this context.

"(ALLAH) Most Gracious is firmly established on the throne (of authority). To Him belongs what is in the heavens and on earth, and all between them,and all beneath the soil. If thou pronounce the word aloud(it is no matter): for verily He Knoweth what is secret and what is yet more hidden. "
[Surah Ta Ha 20:5-7]

If things seem to be wrong in our imperfect vision on this earth, we must remember that ALLAH(Subhana Wa Ta'la),Who encompasses all Creation and sits on the throne of Grace and Mercy,is in command,and our Faith tells us that all must be right. ALLAH's authority is not like an authority on earth, which maybe questioned,or which may not last. His authority is "firmly established".

An exhaustive definition of everything we can conceive of- what is in the heavens, on the earth, or between,or within the bowels of the earth. See also Surah 10:3

"Verily your Lord is ALLAH, Who created the heavens and the earth in six Days,then He established Himself on the Throne (of authority, regulating and governing all things. No intercessor(can plead with Him) except after His leave (hath been obtained). This is ALLAH your Lord; Him therefore serve ye: will yet not receive admonition? "
[Surah Yunus 10:3]

"ALLAH! there is no god but He! To Him belong the Most Beautiful Names. "
[Surah Ta Ha 20:8]

ALLAH(Subhana Wa Ta'la) is all-in-all, and the most beautiful things we can think of are referable to Him. His Names refer to His attributes which are like titles of Honour and Glory.
Say: "Call upon ALLAH, or Call upon Rahman: by whatever name you call upon Him, (it is well): for to Him belong the Most Beautiful Names. Neither speak thy Prayer aloud,nor speak it in a low tone,but seek a middle course between. "
[Surah Al Isra 17:110]
Subhana ALLAH!
