As expected, the Quraish repeatedly broke the terms of the Hudaibiyyah Treaty and continued killing innocent men and women. Therefore, on the morning of Friday, the 20th of Ramadhan, 8 A.H. the Prophet (peace be upon him) entered Makkah and captured the city with hardly a single drop of blood being shed. The Prophet (peace be upon him) forgave all those who had up to then, been bitter enemies of Islam and declared a general amnesty.
The Prophet (peace be upon him) then went into the Ka'bah and destroyed all the idols inside it. The Ka'bah was once again restored to the purpose for which it was built by Prophet Ibrahim, as a place to worship, the one true God, Allah.
One man, trembling with fear on that day, was told by the Prophet (peace be upon him), “Be at ease, and do not be afraid. I am not a king. I am only the son of a woman of the Quraish who used to eat meat dried in the sun.”
Unlike other leaders who arrogantly boast of their victory, the Prophet (peace be upon him) was so humble before Allah that his chin almost touched the back of his camel.
The victory of Makkah had a tremendous impact on the Arabs. It showed that Islam was the religion of Allah and it paved the way for the whole of Arabia to accept the faith.
After the conquest, the Prophet (peace be upon him) returned to Madinah.
