لَوْ خَرَجُوا فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا خِلَالَكُمْ يَبْغُونَكُمُ الْفِتْنَةَ وَفِيكُمْ سَمَّاعُونَ لَهُمْ ۗ وَاللَّهُ عَلِيمٌ بِالظَّالِمِينَ (47)
(9:47) Had they gone forth with you, they would have added nothing but mischief to you and they would have made strenuous efforts to sow discord among your ranks; yet there are among you some who listen to them but Allah knows these mischief-makers full well.
