Quran 9:47 At-Tawbah, ayah 47 of 129

لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا۟ خِلَـٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّـٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ ۝٤٧

9:47 Had they gone forth among you they had added to you naught save trouble and had hurried to and fro among you, seeking to cause sedition among you; and among you there are some who would have listened to them. Allah is Aware of evil-doers.
