Different people have different ideas and impressions about Islam due to existing world conditions. Islam is a continuation of the monolithic belief and was preached by Prophet Muhammad (p.b.u.h.), who was born in Arabia in the year 570 A.D. He started preaching Islam after receiving a divine revelation at the age of 40. The revelation took 23 years to complete, and is the Holy Quran, which still exists in its original text in Arabic. The translations are available in many world languages side by side with the original Arabic text.
