The Koraish Unification of the Arabs in Ohud

In ohud, the korash realized that even if they sent their entire city to medina, it would not eliminate islam. Never had the koraish fought unified in a battle until ohud. Their stalwarts there, their ther noble scions, if you like, rutba, ben rabi ashaba, rabia, omaya, ben halaf, abu jahal himself, all of these major figures, every one of them died. And finally, after being so demoralized, they were forced to acknowledge the superiority of the moslems in treaty of herdabia.
