Why does not God give His provisions abundantly to all His servants

Verse 27 of Chapter 42:

If Allah were to enlarge the provision for His Servants, they would indeed transgress beyond all bounds through the earth; but he sends (it) down in due measure as He pleases. For He is with His Servants Well-acquainted, Watchful.

Does God answer the prayers of those who believe and do good works?

Verse 26 of Chapter 42:

And He listens to those who believe and do deeds of righteousness, and gives them increase of His Bounty: but for the Unbelievers their is a terrible Penalty.

No argument is recommended for believers with those who disagree even after the true knowledge has reached them!

Verses 14-15 of Chapter 42:

And they became divided only after Knowledge reached them,- through selfish envy as between themselves. Had it not been for a Word that went forth before from thy Lord, (tending) to a Term appointed, the matter would have been settled between them: But truly those who have inherited the Book after them are in suspicious (disquieting) doubt concerning it. Now then, for that (reason), call (them to the Faith), and stand steadfast as thou art commanded, nor follow thou their vain desires; but say: "I believe in the Book which Allah has sent down; and I am commanded to judge justly between you. Allah is our Lord and your Lord: for us (is the responsibility for) our deeds, and for you for your deeds. There is no contention between us and you. Allah will bring us together, and to Him is (our) Final Goal.

God prescribed the same way of life for all prophets and their followers!

Verse 13 of Chapter 42:

He has appointed for you the same Way of life which He had ordained for Noah and which (O Muhammad) We have now revealed to you; and which We had already enjoined on Abraham and Moses and Jesus, stressing: "Establish this Way and be not divided in it." The same thing to which you (O Muhammad) are calling the mushriks has set them ill at ease. Allah chooses for Himself whomever He wills, and He guides to His Way only him who turns to Him (in penitence).
