Qur'an 9:47 · At-Tawba

لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًۭا وَلَأَوْضَعُوا۟ خِلَٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّٰلِمِينَ

(47) Had they gone forth with you, they would not have increased you except in confusion, and they would have been active among you, seeking [to cause] you fitnah [i.e., chaos and dissension]. And among you are avid listeners to them. And Allāh is Knowing of the wrongdoers.
