At-Taubah - 9:57

لَوْ يَجِدُونَ مَلْجَأً أَوْ مَغَارَاتٍ أَوْ مُدَّخَلاً لَّوَلَّوْاْ إِلَيْهِ وَهُمْ يَجْمَحُونَ
[9:57]
If they could find a refuge or cave or a place to enter into, they would certainly have turned thereto, running away in all haste.
If they could find a place to flee to, or caves, or a place of concealment, they would turn straightaway thereto, with an obstinate rush.
Had they but found a refuge, or caverns, or a place to enter, they surely had resorted thither swift as runaways.
