Victors are usually proud and happy to take revenge on their victims, but not the Prophet Muhammad (peace be upon him). After his conquest of Makkah, the Prophet (peace be upon him) displayed the utmost humility. When he entered Makkah, his head was bowed so low that people could see his beard touching the camel's saddle. Standing at the door of the Kabah, the Prophet (peace be upon him):
There is none worthy of being served save the one, Allah. He has fulfilled his promise and offered help to his servants. He alone has brought the hosts of enemies low.
The Prophet (peace be upon him) did not claim any credit for the victory: he said it was entirely Allah's doing. And he went on to forgive the Quraysh:
I say to you as Yusuf said to his brothers: Let no reproach be upon you this day. Go, you are free.
Even Uthman ibn Talhah who had once refused the Prophet's (peace be upon him) entry to the Kabah and persecuted him, was later given back the key to the shrine, and it remains with his family to this day.
Then the Prophet Muhammad (peace be upon him) turned to the Kabah and pointed to the idols that had been placed there. He recited from the Quran:
In the name of Allah, the beneficent, the merciful... Truth has come and falsehood has vanished away. Lo! Falsehood is ever bound to vanish.
All the idols crashed to the floor. The Prophet (peace be upon him) and his followers then cleaned and purified the Kabah, and Bilal, who had a strong and beautiful voice, was ordered to climb to its top and give the call to prayer.
The Kabah, the house of Allah, was at last restored to the purpose which it had been built thousands of years, before by the Prophet Ibrahim (peace be upon him) as a safe, holy place for the worship of Allah, our creator. To this day Makkah remains the spiritual centre of Islam.
The Prophet (peace be upon him) returned to Madinah, and the Quraysh became Muslim, and one by one, the rest of the tribes in Arabia declared their faith. As each tribe joined Islam, the Prophet (peace be upon him) sent people acting on his behalf to teach them about Islam, which seemed new to them, but which was actually the completion of the prophetic tradition beginning with Adam and continued by Nuh, Ibrahim, Musa and Isa, upon all of whom be peace. The Prophet (peace be upon him) himself continued teaching, guiding and conveying Allah's instructions to his followers.
But even though he commanded wide power and authority, the Prophet Muhammad (peace be upon him) remained humble and ordinary man. He (peace be upon him) was the ruler of Arabia, but he wore no crown and did not sit on a throne.
