And they have not revered Allah His true reverence), they did not have true knowledge of Him, His Graciousness and Mercy to His servants since they denied the fact that He sent Messengers and revealed Scriptures.

Question: What is the sign of revering Allah His true reverence?

Among this type of wrongdoers is one who turned away from the Prophet's Sunnah and the way of the righteous predecessors. So, he would say: I have a hunch about this matter, or my heart tells me this about such matter. And so, they rule by how they feel in their hearts and by whatever thoughts that come to them. They set aside the rules of Sharia, saying: These rules are meant for the fools and general public, but the elite allies do not need them. Al-Qurtubi: 8/458.

No one does more wrong or greater evil than the one who tells lies against Allah, by attributing to Him words or rulings that have nothing to do with Him.

This is one of the worst of evil deeds. Al-Saadi: 265.

(While the angels are stretching out their hands) tormenting them and striking their faces and their backs, moreover, it is said: Tormenting them by taking their souls. The angels say, (Give up your souls) unwillingly, because the believer' soul is elated for meeting its Lord while the disbeliever' soul hates that. It means that if only you could see that, you would be astonished. Al-Baghawi: 2/47.
Question: What is the difference between the believer and disbeliever at the time of death?

Al-Saadi: 265.
