﴿ لَوْ يَجِدُونَ مَلْجَـًٔا أَوْ مَغَٰرَٰتٍ أَوْ مُدَّخَلًۭا لَّوَلَّوْا۟ إِلَيْهِ وَهُمْ يَجْمَحُونَ ﴾

“if they could but find a place of refuge, or any cavern, or a crevice [in the earth], they would turn towards it in headlong haste.”

If they could find a shelter in which to seek refuge or some caverns underground chambers or any place to enter they would turn and bolt away to it they would hasten to enter it and get away from you with the undeterred speed of an indomitable steed.
