(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:
5. The word: لَذَّةٍ appearing in verse 46: لَذَّةٍ لِّلشَّارِبِينَ (ladhdhati lishsharibin: delicious for those who drink) is essentially a verbal noun which means 'to be tasteful'. Therefore, some commentators have said that, at this place, the adjunct (mudaf) stands elided. Initially, it was: ذات لَذَّةٍ (dhati ladhdhatin: having taste). But, there is no need for this labored approach. First of all, even if 'ladhdhah' is taken to mean nothing but a verbal noun is frequently used in the sense of ismul` fail. In that case, it would mean that it would be 'a taste personified' for those who drink. In addition to that, there is another adjectival form of: لَذَّةٍ : ladhdhatun besides لَذیذُ : ladhidhun - that is, لَذُّ : ladhdhun. It is possible that the word: لَذَّةٍ : ladhdhatun used here may be a feminine form of the same al ladhdhun (Tafsir Qurtubi). In this case, it would mean: 'delicious for those who drink.
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.
