We realize it would be convenient for you to believe, that what you suggest would constitute justification for the mass-murder beheading of little post-pubescent farm boys and their peaceful, faithful, date-farming dads and grandpas, but you need to present some evidence from the Quran or Ishaq, Tabari, Bukhari or Muslim, that suggests that the Quraish were the betrayers rather than as is far more obvious, the ones that were betrayed.
"Thus, if they let you be, and do not make war on you, and offer you peace, Allah does not allow you to harm them" (Surah 4:90).
In the earliest stage of Islam, Muhammad began peacefully calling the people of Mecca to accept Islam. He did this for about 10 years without fighting or killing anyone. At a certain time, however, because of their belief, Muhammad and his followers were strongly opposed. Several Meccan chiefs and leaders formed an alliance a plot an attack against the Muslims. Then, the situation started to become worse until the Muslims were forced to migrate. Muhammad and his followers fled from Mecca to Medina and they were pursued closely by the assassins for days. They were severely tortured, expelled, had their property seized, and even killed to make them give up their religion. Despite all this, Muslims still did not waver from the Islamic principles of peace, non-violence, and passive resistance. In Medina, the Islamic community was established and Muhammad continued his peaceful mission of calling people to Islam.
However, the Quraish alliance was persistent on extinguishing Islam. Several major military campaigns were waged to attack Medina in order to annihilate the Muslims. When the well-equipped armies of aggressors were forming on the horizon, far outnumbering the Muslims, Allah gave Muslims the permission for the first time to defend themselves and their families by taking arms.
Even then, during a war if a Muslim was approached by a pagan asking for asylum, he was ordered to grant it to him, and to give him the opportunity to hear the word of God. Even if the pagan hears the word and does not accept it (meaning he does not convert to Islam), the Muslim is still obliged to protect him as instructed in Surah 9:06 which states,
"If any amongst the pagans ask you for asylum, grant it to him, so that he may hear the word of God, and then escort him to a place of safety. That is because they are a people who do not know."This probably deserves a thread of its own, but I tried to be as brief as possible. See what you can do with it.
