Kur’an 9:47 — sura At-Tawbah, 47. ajet

لَوۡ خَرَجُواْ فِيكُم مَّا زَادُوكُمۡ إِلَّا خَبَالٗا وَلَأَوۡضَعُواْ خِلَٰلَكُمۡ يَبۡغُونَكُمُ ٱلۡفِتۡنَةَ وَفِيكُمۡ سَمَّـٰعُونَ لَهُمۡۗ وَٱللَّهُ عَلِيمُۢ بِٱلظَّـٰلِمِينَ

Da su pošli s vama, bili bi vam samo na smetnji i brzo bi među vas smutnju ubacili, a među vama ima i onih koji ih rado slušaju. A Allah zna nasilnike.

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. And among you are avid listeners to them. And Allah is Knowing of the wrongdoers
