[14].Surah Ibrahim {A.S} [Abraham (PBUH)] : Ayat 44

Ayat 44. And warn (O Muhammad  [SAWW](PBUH) mankind of the Day when the torment will come unto them; then the wrong-doers will say: "Our Lord! Respite us for a little while, we will answer Your Call and follow the Messengers!" (It will be said): "Had you not sworn aforetime that you would not leave (the world for the Hereafter). 

Hazrat Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah  [SAWW](PBUH) said, "Between the two Blowing of the Trumpet there will be an interval of forty.'' The people said, "O Abu Hurairah! Do you mean forty days?'' He said, "I cannot say anything.'' They said, "Do you mean forty years?'' He said, "I cannot say anything.'' They said, "Do you mean forty months?'' He said, "I cannot say anything. The Messenger of Allah  [SAWW](PBUH) added: `Everything of the human body will perish except the last coccyx bone (end part of the spinal cord), and from that bone Allah will reconstruct the whole body. Then Allah will send down water from the sky and people will grow like green vegetables'.''

[Al-Bukhari Book 06, Chapter 60, Hadith # 457]. 

Lesson : as mentioned above in Surah Ibrahim {A.S} Ayat 44. "Had you not sworn aforetime that you would not leave (the world for the Hereafter).

1. When Israfil blows the Trumpet the first time, by Allah's Leave, all those who are in the heavens and on earth will swoon away, except him whom Allah will. This will be the first Blowing. Then, it will be blown a second time, they will become alive and will emerge from their graves. These Blowings are known as the `Blowings of Fainting and Rising'. As regard the interval between these two Blowings, the narrator of the narration, Abu Hurairah (May Allah be pleased with him), could not say anything when he was asked about it; as he himself did not know it. But in other narrations the interval has been mentioned as forty years.

2. The earth eats away the whole body of humans except the bodies of the Prophets. However, only the end part of the spinal cord remains intact. How it remains intact is known to Allah, but from it mankind will be created again.

3. Bodies will rise from the earth as vegetation springs out from the earth after the rainfall.
