Meaning: He would have made their lives full of luxurious things, and given them everything they desire. But what prevented Him from doing that was His mercy towards His servants, lest they hasten to disbelieve and commit many sins because of their love of worldly gain. This indicates that He may withhold some worldly gains from His servants, at society's level, or individuals, in their best interests. Al-Saadi: 765.

A person who lives in prosperity is likely to be distracted from remembering Allah, so, the angels would repel from him, but the devils would cling to him, which would lead him to every evil deed.

If it is asked: Does this person have any excuse because he thinks that he is rightly guided while he is not?

They showed no interest in guidance despite being able to do so, but they chose falsehood. So, the fault is theirs and the error is theirs. Al-Saadi: 766.

This is said to the disbelievers in the Hereafter, which means that they will not be consoled by sharing the punishment, similar to the relief that an afflicted person, in worldly life, would feel when seeing others with the same affliction. Ibn Juzay: 2/314.

Question: What is the main task of those who preach others to Allah?

The pronoun in (it is) refers to the Quran or Islam. (Remembrance) means honor. (Your people), Quraish and the rest of the Arab people, as they, through Islam, have attained honor in worldly life and the Hereafter. It should suffice you that they had conquered the east and west of the land. Ibn Juzay: 2/314.
Question: What is the honor attained by the Arabs when they adhered to Islam?

Those who live in luxury often disdain whoever comes to them, and they persist on doing that until the Almighty subjugates them by the Message carried out by His Messengers, either by destroying them or something else despite their power.

Al-Biqai: 7/33.
Question: What is the attitude of the affluent ones toward those who advise them? What is Allah’s way in deciding the end of each group?
