Thus, summing-up the meanings of these words used in the Holy Quran, and connecting it with other facts described in other verses and hadiths, a clear picture of the Doomsday can be visualized. When the Doomsday will occur ? Scientists strongly believe that one day the world will cer tainly come to an end but do not know when it will precisely happen.

It is vir tually impossible to know the timings of the Doomsday. From the Quran and the hadith, it is clear that the exact timings of the Doomsday is an absolute Divine secret. No one except Allah (swt) knows the time of Qiyamat. Quran clearly tells us, why the time of the Qiyamat is held in secret. "The Hour of Doom is sure to come. But I choose to keep it hidden, so that every soul may be rewarded for its efforts". (20:15) "They question you (Muhammad) about the Hour of Doom: When shall it be ?

(say) you have no knowledge to say anything about it. Allah alone knows when it will come. You are but a Warner for those who fear". (79:42-44) The Doomsday will come suddenly at its own time fixed by Allah (swt). The time is fixed but no one knows it except Him. "They ask you (Muhammad) about the Hour ( of Doom ) and when it is to come. Say : None knows except my Lord. He alone will reveal it at the appointed time. A fateful hour it shall be , both in the heavens and the earth.

It will come suddenly." (7:187) " People ask you about the Hour of Dooms. Say: the knowledge of it is with Allah alone. Who knows? it may well be that it is near at hand". (33:63) What will be the length of the Doomsday? No one knows the actual length of the Doomsday. However, we can guess a figure from the reliable data available to us. The Doomsday will cause complete destruction of the universe. There are billions of galaxies in the universe and each galaxy contains billions of stars.
