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. Through the Holy Prophet (Sallallahu alaihi wa sallam), Allah Most High has granted many bounties to this Ummah. Allah Most High says about the martyrs:
And say not of those who are slain in the way of Allah: "They are dead." Nay, they are living, though ye perceive (it) not. (154) Surah Baqarah (2:154)
Through this verse of the Holy Quran, we understand the martyrs are alive. The Prophets are the best of all the creation. It is against their honor that their followers get martyred and stay alive and the Prophets themselves whose teaching inspired them to attain martyrdom do not reach this high station. Thus, the Prophets are all the more alive and with even more perfection. As Imam Zurqani (May Allah shower His mercy on him) has written in the commentary of Mawahib Ladunniya, Vol. 7, Pg No: 368.
The Hadith explicitly mention that the Prophets are alive. There is a Hadith in Musnad Abu Ya’ala:
Translation: It is narrated on the authority of Hadhrat Anas (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: The Prophets are alive and offer Salaat in their graves. (Musnad Abu Ya’ala, Hadith No: 3331, Musnad Anas Raziallahu Anhu)
Imam Haithami (May Allah shower His mercy on him) writes in Majma’ Uz Zawaaid after mentioning this Hadith:
Translation: All the narrators of this Hadith are veritable and reliable. (Majma’ Uz Zawaaid, Vol. 8, Pg No: 210)
There is another Hadith:
Translation: It is narrated on the authority of Hadhrat ‘Aus bin ‘Aus (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: The most superior day among your days is Friday. On this day, Hadhrat Adam (May peace be upon him) was born. On this day he passed away to the presence of Allah, on this day the horn (Soor) will be blown and on this day, unconsciousness will overwhelm people.
Thus, on this day, recite Durood profusely, as your Durood is presented to me. The narrator says: The Companions requested: O Prophet of Allah (Sallallahu alaihi wa sallam), how is our Durood presented to You after you meet Allah? The Holy Prophet (Sallallahu alaihi wa sallam) said: The truth is that Allah Most High has forbidden the bodies of the Prophets on the earth.

(Sunan Ibn Majah, Hadith No: 1706, Jame’ Ul Ahadith, 4320, Jame’ Ul Kabeer Lis Suyuti, Hadith No: 61)
There is a Hadith in Sahih Muslim:
Translation: It is narrated on the authority of Hadhrat Anas Bin Malik (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: I passed by Hadhrat Moosa (May peace be upon him) and he was offering Salaat in his grave. (Sahih Muslim, Hadith No: 165)
Please see part of a lengthy Hadith in Sahih Ibn Hibban about the aforementioned Hadith:
Translation: When the Holy Prophet (Sallallahu alaihi wa sallam) entered Bait Ul Muqaddis and then ascended the skies, then Hadhrat Moosa (May peace be upon him) also came. The Holy Prophet (Sallallahu alaihi wa sallam) met him on the 6th heaven and they conversed………………(Sahih Ibn Hibban, Hadith No: 50)
It is mentioned in this Hadith that on the first heaven, the Holy Prophet (Sallallahu alaihi wa sallam) met Hadhrat Adam (May peace be upon him), on the 2nd Hadhrat Yahya (May peace be upon him), on the 3rd Hadhrat Yousuf (May peace be upon him), on the 4th Hadhrat Idris (May peace be upon him), on the 5th, Hadhrat Harun (May peace be upon him), on the 6th Hadhrat Moosa (May peace be upon him) and on the 7th Hadhrat Ibrahim (May peace be upon him).
This Hadith shows that the Prophets are alive. They offer Salaat in the same way as they offered it in this earthly life and move from one place to another.
Imam Zurqani (May Allah shower His mercy on him) says in Sharh Mawahib:
Translation: It is given in Fatawa Ramliya that the bodies of the Prophets, the martyrs and the scholars do not decay after death. The Prophets and the martyrs eat and drink in their graves, offer Salaat, fast and go for Haj. (Sharh Zurqani ‘Alal Mawahib, Vol. 7, Pg No: 369)
