The Prophet is sent to the Arabian peninsula :
Allah chose the Arabs to receive the call of Islam and to convey it to the furthest corners of the world. These people were simple-hearted with no complicated ideologies which would have been difficult to remove. While the Greeks, Persians and people of India were arrogant about their many sciences, their fine literature and their splendid
civilization, the Arabs followed only simple traditions related to their desert existence. It was not difficult to sweep these away and replace them with a fresh vision.
The Arabs were in a natural state. When it was difficult for them to grasp the truth, they fought it. However, when the covering was removed from their eyes, they welcomed the new beginning and, having embraced it, would risk their lives for it. They were honest and trustworthy, hardy, courageous and fine horsemen. They also possessed a will of iron.
In Makkah, a city in the Arabian peninsula, was the Ka'bah which had been built by Ibrahim and Isma'il (peace be upon them). In it, Allah alone was to be worshipped and it was to be a centre for calling people to
Tauheed for all time.
Tauheed, meaning the Oneness of Allah, is in sharp contrast with the worship of idols.
The first house established for people was that at Makkah, a blessed place and a guidance for the worlds. (sura 3:v 96)
