In the peace agreement of Hudaybiyah...
In the peace agreement of Hudaybiyah, [^3] the Holy Prophet of Islam undertook that no Muslimwould shelter any of the infidel Makkans even if they became Muslims before or at the time of seeking refuge with the Muslims in Medina and would return them to Makkah, and he stood by his promise. [^4] If the Holy Prophet had wished, he could have taken the same promise from his enemies that if a person left Islam and sought refuge with the infidels of Makkah, he would be returned to Medina.
When Makkah was conquered by the Prophet and his followers, he gave the Quraysh freedom of choice. He did not force anybody to adopt Islam. He wanted them to become Muslims as a result of their true understanding of Islam and of their own free will, not by force. He ordered the Muslims not to kill anybody in Makkah except for a few who were constantly causing trouble for the Muslims.
[^5] When the infidels asked him for refuge, he would give them refuge and the opportunity to study Islam and then to submit to it freely. For instance, Safwan ibn Umayyah fled to Jeddah when Makkah was conquered by the Muslims. When some people asked the Holy Prophet for refuge on his behalf, he sent his turban for him as a sign of refuge to give him immunity on returning to Makkah. Safwan returned from Jeddah and asked the Prophet to give him a respite of two months.
He agreed to his request and gave him a respite of four months. And Safwan accompanied the Holy Prophet of Islam to Hunayn and Ta'if and finally discarded infidelity and submitted to Islam of his own free will." [^6] Conclusion We conclude that in Islam, the sword is resorted to only in dealing with those who have realized the truth and yet fight it and thus try to hinder others from achieving salvation, and that force is applied to banish tyranny, to release the oppressed, and to create favourable conditions for human progress and evolution.
The sincere and loyal faith of the Muslims at the beginning of Islam and their resistance to all torture and hardship are themselves the best testimonies to the fact that Islam was not promoted by force. History bears witness to this reality: that the Muslims at the beginning of Islam were so devoted to their faith that they persevered in it through their struggles no matter what torture arid torment the infidels inflicted upon them.
Many of them even left their homeland and migrated to other places. The Ethiopian Bilal was among those who took the lead in accepting Islam.
