«إن هذا الأمر في قريش لا يعاديهم أحد إلا كبه الله على وجهه ما أقاموا الدين»
The Prophet (peace and blessings be upon him) said:
"Indeed, this matter (of rule and caliphate) will remain among Quraysh; whoever shows enmity to them, Allah Almighty will throw him down on his face, as long as they keep the religion established."
