Quran 18:16

وَإِذِ ٱعۡتَزَلۡتُمُوهُمۡ وَمَا يَعۡبُدُونَ إِلَّا ٱللَّهَ فَأۡوُ ۥۤاْ إِلَى ٱلۡكَهۡفِ يَنشُرۡ لَكُمۡ رَبُّكُم مِّن رَّحۡمَتِهِۦ وَيُهَيِّئۡ لَكُم مِّنۡ أَمۡرِكُم مِّرۡفَقً۬ا ١٦

"Since you wish to avoid them, and their worshipping of other than ALLAH, let us take refuge in the cave. May your Lord shower you with His mercy and direct you to the right decision."
