Is the body of a martyr not decomposed like the bodies of the prophets?

The questioner : They say that the body of a martyr does not decompose, meaning like the bodies of other deceased people?

The Shaykh : There is no legal evidence for this claim...

The questioner : Just as they say that it is the grave of our master, the uncle of the Messenger (peace and blessings be upon him)...

The Shaykh : Al-Abbas, and not Hamzah?

The questioner : Hamzah.

The Shaykh : I tell you, there is no evidence in the Shari'ah that informs us that the bodies of martyrs do not decay like the bodies of the prophets. We have a text that Allah (Mighty and Majestic) forbade the earth to consume the bodies of the prophets. There is absolutely no such text regarding martyrs. However, what happened is that in early Islamic history, due to excavations, the body of some martyrs was found as it was. This is true and it did happen, but this does not give us a rule that every martyr's body does not decompose. In fact, some bodies of non-martyrs have been found [intact]. As I said earlier, this may be due to the nature of the soil, or Allah (Mighty and Majestic), who is All-Aware of the conditions of the dead, may honor some of them by keeping their bodies as they were in life. It may be a karamah (a miracle granted to a righteous person) from Allah. Therefore, whether a person is a martyr or a righteous person who is not a martyr, it is not permissible for us to take from this a general rule. We do not say about Allah what we do not know. We say that Allah forbade the earth to consume the bodies of the prophets, but for those other than the prophets, we have no evidence that their bodies remain. Yes.
