Why must "everything taste death"? Does Allah allow death without a purpose. Is it "just because"?
If death is not a consequence of someone's action, why is death a punishment for some of man's sins in the Quran or the Torah?
"By the passage of time*1, all of the humankind are in a state of great loss*2, except for those who come to the correct belief*3 and do the deeds of righteousness; and encourage and exhort one another to Truth*4 and encourage and exhort one another to steadfast patience."
1. Allah swears an oath of great consequence
2. Meaning "Hell" as a result of their dealings while on earth
3. Oneness of Allah (Tawheed or monotheism)
4. Here "Truth" means anything and everything pertaining to pure montheism (see: Islam)
From the above quoted portion of the Quran and verses related to it, the scholars of Islam have concluded the following:
A) All of us are born with a purpose to be fulfilled before death – Worship of the One True God, Alone and on His terms and conditions.
Note: Quran says: "Allah only created you all for the purpose of worshipping Him."
B) All of us will die and be in the grave.
Note: Quran says: "Every soul shall taste death."
C) All of us (believers and non-believers) will be recreated (resurrected) on the Day of Judgment.
Note: Quran says: "Surely from Allah you came and to Him is your return."
And "Do they not think that they will be resurrected, on a Great Day? The Day when all mankind will stand before the Lord of the Worlds?"
D) Each person will receive his/her "Book of Record" (listing of all their deeds).
Note: Quran says: "Nay! Truly, the Record of the wicked is a Preserved Record."
And "Those who receive their books in their right hands will be successful." and "Those who receive their books behind their backs will be the losers."
E) Each person will be held accountable for what he/she has done.
Note: Quran says: "Every person will see any good they have done, even an atom's weight. Every person will see any evil they have done, even an atom's weight."
F) None will take away the sins or punishment for another.
Note: Quran says: "Allah does not burden a person beyond his ability. He will be rewarded for that which he has earned, and punished for that which he has earned."
G) None will make intercession with the Almighty except as He Wills.
Note: Quran says: "Who is there that could come between Allah and what He has created except that He give them permission?"
H) The final destination of Heaven or Hell will be made known then.
Note: Quran says: "Verily, You shall see the blazing Fire (Hell)."
I) None will enter the Paradise except by the Mercy of Allah.
Note: Prophet Muhammad, peace be upon him, said: “None shall enter the Jennah (Paradise) except with the Mercy of Allah.” When asked by his companions: “Even you? O, prophet of Allah?” And He replied: “Even me.”
J) None will enter the Fire except those who have earned it.
Note: Quran says: "Therefore, I have warned you of a blazing Fire (Hell). None shall enter it except the most wrected.http://islamtomorrow.com/death.htm
