When the clans were driven away, I heard the Prophet ﷺ saying, "From now onwards we will go to attack them (i.e. the infidels) and they will not come to attack us, but we will go to them."
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ حِينَ أَجْلَى الأَحْزَابُ عَنْهُ الآنَ نَغْزُوهُمْ وَلاَ يَغْزُونَنَا نَحْنُ نَسِيرُ إِلَيْهِمْ
