The reason why the believing women were not handed back was either because they were not  originally  included in the terms of the treaty, which mentioned only men, or because the Qur’ân abrogated any  terms dealing with women in the verse:
“O Prophet! When believing women come to you to give you the Bai‘a (Pledge), that they will not  associate anything in worship with Allâh …” 60:12
This is the verse which forbade Muslim women from marrying disbelieving men. Likewise, Muslim men  were commanded to terminate their marriages to disbelieving women. In compliance with this  injunction, ‘Umar bin Al-Khattab divorced two wives he had married before he embraced Islam;
Mu‘awiyah married the first woman, and Safwan bin Omaiyah married the second.
ALHUDAIBIYAH TREATY: SOCIO-POLITICAL IMPACT:
A series of events confirmed the profound wisdom and splendid results of the peace treaty which Allâh  called “a manifest victory”. How could it be otherwise when Quraish had recognized the legitimate
Muslims’ existence on the scene of political life in Arabia, and began to deal with the believers on  equal  terms. Quraish in the light of the articles of the treaty, had indirectly relinquished its claim to religious  leadership, and admitted that they were no longer interested in people other than Quraish, and  washed  their hands of any sort of intervention in the religious future of the Arabian Peninsula. The Muslims did  not have in mind to seize people’s property or kill them through bloody wars, nor did they ever think  of  pursuing any coercive approaches in their endeavours to propagate Islam, on the contrary, their sole  target was to provide an atmosphere of freedom as regards ideology or religion:
“Then whosoever wills, let him believe, and whosoever wills, let him disbelieve.” 18:29
The Muslims, on the other hand, had the opportunity to spread Islam over areas not then explored.
When there was armistice, war was abolished, and men met and consulted together, none talked  about
Islam intelligently without entering it; within the two years following the conclusion of the treaty  double  as many entered Islam as ever before. This is supported by the fact that the Prophet (Peace be upon  him) went out to Al-Hudaibiyah with only 1,400 men, but when he set out to liberate Makkah, two  years later, he had 10,000 men with him.
The article of the treaty pertaining to cessation of hostilities for ten years points directly to the utter  failure of political haughtiness exercised by Quraish and its allies, and functions as evidence of the  collapse and impotence of the war instigator.
Qhad been obliged to lose those advantages in return for one seemingly in its favour but does not  actually bear any harm against the Muslims, i.e., the article that speaks of handing over believing men  who seek refuge with the Muslims without their guardians’ consent to Quraish. At first glance, it was a  most distressing clause and was considered objectionable in the Muslim camp. However, in the course  of events, it proved to be a great blessing. The Muslims sent back to Makkah were not likely to  renounce the blessings of Islam; contrariwise, those very Muslims turned out to be centres of  influence  for Islam. It was impossible to think that they would become apostates or renegades. The wisdom  behind this truce assumed its full dimensions in some subsequent events. After the Prophet (Peace be  upon him) had reached Madinah, Abu Baseer, who had escaped from Quraish, came to him as a
Muslim; Quraish sent two men demanding his return, so the Prophet (Peace be upon him) handed him  over to them. On the way to Makkah, Abu Baseer managed to kill one of them, and the other one fled  to Madinah with Abu Baseer in pursuit. When he reached the Prophet (Peace be upon him), he said,
“Your obligation is over and Allâh has freed you from it. You duly handed me over to the men, and
Allâh  has rescued me from them.” The Prophet (Peace be upon him) said, “Woe is his mother, he would  have  kindled a war if there had been others with him.” When he heard that, he knew that he would be  handed back to them, so he fled from Madinah and went as far as Saif Al-Bahr. The other Muslims who  were oppressed in Makkah began to escape to Abu Baseer. He was joined by Abu Jandal and others  until a fair-sized colony was formed and soon sought revenge on Quraish and started to intercept their  caravans. The pagans of Makkah finding themselves unable to control those exiled colonists, begged  the Prophet (Peace be upon him) to do away with the clause which governed the extradition. They  implored him by Allâh and by their ties of kinship to send for the group, saying that whoever joined
