Quran 9:47 from Surah At-Tawba on Divine Marvels.
لَوۡ خَرَجُواْ فِيكُم مَّا زَادُوكُمۡ إِلَّا خَبَالٗا وَلَأَوۡضَعُواْ خِلَٰلَكُمۡ يَبۡغُونَكُمُ ٱلۡفِتۡنَةَ وَفِيكُمۡ سَمَّٰعُونَ لَهُمۡۗ وَٱللَّهُ عَلِيمُۢ بِٱلظَّٰلِمِينَ
English translation: If they (had) gone forth with you not they (would) have increased you except (in) confusion and would have been active in your midst seeking (for) you dissension And among you (are some) who would have listened to them And Allah (is) All-Knower of the wrongdoers
Transliteration: law kharaju fikum ma zadukum illa khabalan wala-awda'u khilalakum yabghunakumu al-fit'nata wafikum samma'una lahum wal-lahu alimun bil-zalimina
