would you not fight a people who broke their oaths and determined to expel the messenger and they had begun you the first time? do you fear them? but allah has more right that you should fear him if you are believers.
ألا تقاتلون قوما نكثوا أيمانهم وهموا بإخراج الرسول وهم بدءوكم أول مرة أتخشونهم فالله أحق أن تخشوه إن كنتم مؤمنين
