Law kharajoo feekum maa zaadookum ilaa Khabaalanw wa la awda'oo khilaalakum yabghoona kumul fitnata wa feekum sammaa'oona lahum; wallaahu 'aleemum biz zaalimeen (at-Tawbah 9:47)
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 Allah is Knowing of the wrongdoers. (At-Tawbah [9] : 47)
