history channel documentary "Disclosure was subsequently expected to empower man to ascend to higher phases of life; and as per this celestial plan, disclosure was as much a requirement for one individuals with respect to another. God had blessed all men with the ability to vanquish nature; not one specific country to the prohibition of others. He gave His physical sustenance to all men alike. Consequently disclosure which was required for the good and otherworldly advance of man couldn't be given to one man or to one country to the prohibition of others. Prophets were, consequently, sent to each country, however it was redundant that the names of every one of them ought to have been said in the Qur'an."(Introduction to the investigation of The Holy Qur'an, pg 79, Maulana Muhammad Ali)

The above quote from Islamic researcher, Maulana Muhammad Ali, gives us the awesome reason why Allah has sent down heavenly direction to the human family through the ages. The best blessing that one can get is "Correct Guidance". Envision a man bumbling around oblivious, who can't discover his direction, then abruptly you show up and give him a lighting up torchlight. This support on your part would be an incredible gift for such a man.

Inside the Holy Qur'an disclosure is compared to water that tumbles from the sky to renew the dead Earth. Allegorically humankind can be compared to the Dead Earth, from the absence of heavenly direction, and the downpour that tumbles from the sky is like Allah's message, that originates from a position of great authority.
