The distinctive demise of the Holy Prophet (Sallallahu alaihi wa sallam) and His life beyond it

 The life of the Holy Prophet (Sallallahu alaihi wa sallam) after His demise

Allah Most High has granted superiority to the Prophets (Sallallahu alaihi wa sallam) over all other creation and has granted them special honor and perfection.  He has made the Holy Prophet (Sallallahu alaihi wa sallam) the leader of all the Prophets and has culminated Prophethood on Him.  It is accepted universally by all Muslims that the Prophets are alive in their graves.  It is proven by the Holy Quran and the Hadith:

And it is not (at all lawful) for you that you cause inconvenience to the Holy Messenger of Allah (blessings and peace be upon him), nor is this (lawful) that you marry his (pure) wives after him, till the end of time. Surely, it is the most grievous sin in the sight of Allah.  Surah Ahzaab (33:53)

In this verse of the Holy Quran, Almighty Allah has strictly prohibited the Ummah from marrying any of the wives of the Holy Prophet (Sallallahu alaihi wa sallam).  It is not permissible for any person to marry any of the wives of the Holy Prophet (Sallallahu alaihi wa sallam)

It is axiomatic in the science of jurisprudence (Fiqh) that when a person dies, the bond of marriage is undone.  After the Iddat (the mandatory period after death of husband or divorce), the woman is entitled to marry anyone.  On the other hand, if the husband is alive, no one can marry his wife.  The strict prohibition in the aforementioned verse of the Holy Quran is a clear proof after passing away, the Holy Prophet (Sallallahu alaihi wa sallam) is alive in the netherworld with distinctive grandeur.  There are various Hadith about this:

There is a Hadith in Sunan Ibn Majah:

Translation: It is narrated on the authority of Hadhrat Abu Darda (May Allah be well pleased with him), he says:  The Holy Prophet (Sallallahu alaihi wa sallam) said:  Almighty Allah has prohibited the earth to disturb the bodies of the Holy Prophet (Sallallahu alaihi wa sallam).  The Prophets of Allah are alive and receive sustenance.  (Sunan Ibn Majah, Hadith No. 1706)
