وَإِذِ اعْتَزَلْتُمُوهُمْ وَمَا يَعْبُدُونَ إِلَّا اللَّهَ فَأْوُوا إِلَى الْكَهْفِ يَنشُرْ لَكُمْ رَبُّكُم مِّن رَّحْمَتِهِ وَيُهَيِّئْ لَكُم مِّنْ أَمْرِكُم مِّرْفَقًا
Waithi iAAtazaltumoohum wama yaAAbudoona illa Allaha fawoo ila alkahfi yanshur lakum rabbukum min rahmatihi wayuhayyi lakum min amrikum mirfaqan
"When ye turn away from them and the things they worship other than Allah, betake yourselves to the Cave: Your Lord will shower His mercies on you and disposes of your affair towards comfort and ease."
