إِنَّ الْمُتَّقِينَ فِي ظِلَالٍ وَعُيُونٍ
Indeed, the righteous will be among shades and springs
وَفَوَاكِهَ مِمَّا يَشْتَهُونَ
And fruits from whatever they desire
كُلُوا وَاشْرَبُوا هَنِيئًا بِمَا كُنتُمْ تَعْمَلُونَ
[Being told], “Eat and drink in satisfaction for what you used to do.”
إِنَّا كَذَٰلِكَ نَجْزِي الْمُحْسِنِينَ
Indeed, We thus reward the doers of good.
وَيْلٌ يَوْمَئِذٍ لِّلْمُكَذِّبِينَ
Woe, that Day, to the deniers.
Allah informs His servants that those who have taqwa and worship Him by performing the obligations and abandoning the forbidden things will be in gardens and springs on the Day of Judgment. This means their condition will be opposite of the wretched people because they refrained from denying the Hereafter and accepted it and passed their life in the world with the belief that in the Hereafter they would have to render an account of their word and deed and their conduct and character.
They will be presented with different varieties of fruits and asked to eat their fill. This will be said to them out of kindness for them. Re-establishing what He has previously mentioned, “Verily, thus We reward the Muhsinoon (good-doers),” (77: 44) meaning this is Our reward for whoever does good deeds.
Therefore, “Woe that Day to the deniers,” meaning one of their afflictions will be that after their crimes have been proven and established they will not even be in a position to open their mouths to put forward a plea in self defense, and shall ultimately become fuel of Hell. Their other affliction, and by far the worse will be that they will see the same believers enjoying themselves in Paradise, whom they had been opposing and resisting and mocking throughout their lives as foolish, narrow-minded, mean and old fashioned people.
