Doors of Heaven shall not open for Those Who deny Allah's Ayat, and They shall never enter Paradise

Allah said,

لاَ تُفَتَّحُ لَهُمْ أَبْوَبُ السَّمَآءِ

Commentary

Mentioned first in the set of verses cited above (35-37) is a pledge taken from every human being in the world of spirits, before being born into the material world. The pledge envisaged that they would, when the prophets of Allah come to them with Divine guidance and injunctions, listen to them in earnest and act accordingly. They were also told that those who abide by the pledge and fulfill what it entails, will have their salvation from sorrows and deserve eternal peace and comfort. And conversely, those who belie prophets or rebel against injunctions they bring shall have the eternal punishment of Jahannam waiting for them. The later set of verses presents what actually happened when different groups of human beings came into the world and started acting differently. Some of them threw the pledge behind their backs and settled to oppose it. Others held to it and acted righteously. The ultimate end of the two groups and the reward and punishment for them has been described in the later four verses (40-43).
