(Verily, you are going to taste the painful torment; and you will be requited nothing except for what you used to do.) Then He makes an exception in the case of His sincerely believing servants. This is like the Ayat:
7. In verse 48, it was said: قَاصِرَاتُ الطَّرْفِ (restricting their gazes). This is an attribute of the hurs or houris of Jannah - wide eyes with lowered gaze. It means that except for the mate to whom Allah Ta’ ala gives them in marital bond, they will not raise their eyes to cast a look at any other male. 'Allamah Ibn-ul-Jauzi reports: These women will tell their spouses, 'By the honor of our Lord, I see no one better than you in this Jannah. Praised be Allah who made me your spouse and made you, mine.'
` Allamah Ibn-ul-Jauzi has given yet another sense of 'those with lowered gaze' when he says that they will cause the gaze of their spouses remain lowered. In other words, they will be so beautiful and so faithful that their spouses would simply not have a wish to look at anyone else. (Tafsir Zad-ul-Masir , pages 57, 58, volume 8)
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 39–48
When they were told that there was nobody worth worshipping except God, they behaved haughtily. This does not mean that their haughty behaviour was directed against God. The majesty of God is too lofty to allow any individual to be so presumptuous. Their haughty behaviour, in fact, was aimed at His messenger. The leaders in whose name others indulged in polytheistic acts, were adversely affected by the Prophet’s call for belief in the oneness of God. On the one hand was the Prophet and on the other, the polytheistic leaders. Since the Prophet appeared to be of a lesser stature than the leaders, most people ignored him, considering him a person of little or no account. The force of argument was undoubtedly on the side of the Prophet, but apparent greatness seemed to reside in their leaders and history is replete with examples where the force of reason has proved ineffective in the face of apparent greatness.
