16:68
وَأَوْحَى رَبُّكَ إِلَى النَّحْلِ أَنِ اتَّخِذِي مِنَ الْجِبَالِ بُيُوتا ً وَمِنَ الشَّجَرِ وَمِمَّا يَعْرِشُونَ
Wa 'Awĥá Rabbuka 'Ilá An-Naĥli 'Ani Attakhidhī Mina Al-Jibāli Buyūtāan Wa Mina Ash-Shajari Wa Mimmā Ya`rishūna 

And your Lord inspired to the bees: "You shall take homes of the mountains and of the trees and of what they erect."
