" Quraysh, who had shown throughout the day that they were still in thrall to the overbearing haughtiness and intransigence of the jahiliyyah, a stubborn resistance to anything that might injure their sense of honor or their traditional way of life. They had even been ready to massacre the innocent unarmed pilgrims rather than accept the “humiliation” of admitting them to the Haram. When in the hearts of those who persist in unbelief arose the characteristic arrogance, the arrogance of jahiliyyah, then God sent down his peace of soul (sakinah) upon His Messenger and upon the believers, and imposed upon them the formula of self-restraint (hilm), for that was most befitting to them and they were most suited for that.31 "
