Question:  Can the bodies of the Prophets be consumed by earth after their burials?

Answer:  After analysing many books of ahadith in regards to the above issue, we find the following from some of the Sunan books of ahadith which is below:

Narrated ‘Aws ibn Aws r.a: “The Prophet (pbuh) said: Among the most excellent of your days is Friday; on it Adam was created, on it he died, on it the last trumpet will be blown, and on it the shout will be made, so invoke more blessings on me that day, for your blessings will be submitted to me. The people asked: Messenger of Allah, how can it be that our blessings will be submitted to you while your body is decayed? He replied: Allah, the Exalted, has prohibited the earth from consuming the bodies of Prophets.
