The Hadith:
The Prophet peace be upon him says: (The Islam will spread in all places that have day and night).
The explanation of the Hadith:
This is an amazing prophetic miracle, the Prophet peace be upon him tells us about the rapid spread of Islam and that this religion will cover all parts of the globe. And this is what we will learn through the recent statistics on the number of Muslims all over the world.
Islam started 1400 years ago with only one man who is the Prophet Muhammad peace be upon him and the number of Muslims today became more than one thousand and four hundred million Muslims!! So what is the secret of this amazing spreading, and what does the global statistics say on the number of Muslims in the world today?
Scientific facts:
Today there are more than 4200 religions in the world! The statistics say that Islam is the fastest spreading among all religions in the world! In 1999, the number of Muslims in the world was 1200 million Muslims. But now Islam is spreading in all continents of the world, as the number of Muslims in 1997 in the six continents was: 780 million in Asia, 308 million in Africa, 32 million in Europe, 7 million in America and 385 thousand in Australia.
In 1900, the number of Muslims all over the world was less than half the number of Christians but in 2025, the number of Muslims will become greater than the number of Christians because of the significant growth of Islamic religion. And this is the highest rate of growth in the world!
The Prophet peace be upon him talked about an amazing prophetic miracle that Islam will spread in all parts of the earth, He peace be upon him says: (The Islam will spread in all places that have day and night). And this means that Islam will reach any area of land that has day and night and this is what really happened as nowadays there are Muslims all over the world.
So if we bear in mind that this Hadith has been said by the Prophet peace be upon him at the time when Muslims were weak and few where no one expected that Islam will spread all over the world, we realize the greatness of the miracle. This Hadith came to comfort the believers for their weakness and fewness in number. And if Muhammad peace be upon him wasn't a messenger from Allah, he wouldn't have dared to tell his companions that Islam will spread all over the world, as how could he be sure of that?
The point of inimitability:
Therefore we can say that this Hadith is a scientific miracle for the Prophet peace be upon him because we cannot imagine that a man calling for a new religion with only few people believing him can say these words unless he was confident that this religion will not only spread but will be the most widely spread and no one could have this confidence unless he was inspired from God, which means that he is a messenger of Almighty God.
And in this fact a reply to all those who claim that the Quran was written by Muhammad peace be upon him because it is impossible for anyone to predict that Islam will spread in this amazing way but God be he exalted told him this to reassure him that this religion will spread in all the places that have day and night
