The Quran

۞ لَئِن لَم يَنتَهِ المُنافِقونَ وَالَّذينَ في قُلوبِهِم مَرَضٌ وَالمُرجِفونَ فِي المَدينَةِ لَنُغرِيَنَّكَ بِهِم ثُمَّ لا يُجاوِرونَكَ فيها إِلّا قَليلًا

I.e., "there will be open warfare between thee and them", which will result in their expulsion from Medina: a prediction which was fulfilled in the course of time.
