Quran 40:11

40:11 The disbelievers experience two deaths while the righteous believers do not taste death beyond the death we already experienced (see verse 44:56).

The reason for going to Hell is obvious; even those who believe in Allah associate others with Him (see 39:45).

40:10 + 40:11 - The Proof:

Revealed: For both verses, the messenger’s letters are 33 and 34 to reveal the diff. of 1.

40:10 - The Proof:

Revealed: Up to the Sacred Name of Allah, the messenger’s letters are 14 and in the remaining verse, the messenger’s letters are 19, revealing the Sacred Sign and Miracle of 14 and 19.

40:11 - The Proof. The disbelievers and idol worshippers have been exposed:

40:11 Part 1: They will say, "Our Lord, You have put us to death twice, and You gave us two lives."

40:11 Part 2: "Now we have confessed our sins. Is there any way out?"

Revealed: The Allah letters are 10 and 8 in each part revealing the diff. of 2 to expose the idolatry committed by the disbelievers who rejected the Absolute Authority of Allah.

Revealed: The messenger’s letters are 18 and 16 in each part confirming the idolatry of the disbelievers through the messenger’s letters. The idol worshippers failed to believe in the messenger and in the proofs and revelations that Allah out of His mercy sent down through him in order to test the people whether they believe in "Allah Alone" - "Allah Wahdahoo" or not.
