They worked as preachers inside the heart of Mecca and this work had a great effect to even the way to the great conquest which had taken place without fighting or resistance. One of the advantages of the peace was the mere meeting between the Prophet (s) and the polytheists in al-Hudaybiya. The polytheists met the Prophet (s) face to face and saw his great personality and high morals and guidance which most of Quraysh had known nothing about especially the youths.

Abu Jahl, al-Waleed, Abu Sufyan, Shayba, Utba and their likes of the idolaters had tried their best to defame the Prophet (s) and they could poison the public opinion. They had done whatever they could in order to put out the light of Allah with their mouths, and Allah would not consent save to perfect His light.

They went to where he had immigrated to kill him with his companions and to do away with the people who had protected and supported him but Allah had granted him victory in Badr, Uhud and al-Ahzab; (So the roots of the people who were unjust were cut off; and all praise is due to Allah, the Lord of the worlds).

The people of Mecca, after those wars, remained on their deviate opinion concerning the Prophet (s) for they had not seen him after his emigration to Medina and they had not known about him except what the fabricators spread of false news but on the day of al-Hudaybiya when they mixed with him and with his companions they realized his great morals and high personality. Whenever they treated him severely and did bad to him, he treated them kindly and did good to them.

If they were severe and harsh towards him, he would be kind and merciful to them. He kept on meeting their bad doings with good doings. He followed the saying of Allah: “Repel (evil) with what is best, when lo! he between whom and you was enmity would be as if he were a warm friend. And none are made to receive it but those who are patient, and none are made to receive it but those who have a mighty good fortune.

Qur'an, 41:34-35” (208) The Prophet (s) was able at that time to enter Mecca and to visit the Kaaba by force because Allah had said concerning this event: “And if those who disbelieve fought you, they would certainly turn (their) backs, then they would not find any protector or a helper. Qur'an, 48:22” and: “And He it is Who held back their hands from you and your hands from them in the valley of Mecca after He had given you victory over them.
