Sura al-Faṭīr 35:27

أَلَمْ تَرَ أَنَّ ٱللَّـهَ أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءً فَأَخْرَجْنَا بِهِۦ ثَمَرَٰتٍ مُّخْتَلِفًا أَلْوَٰنُهَا وَمِنَ ٱلْجِبَالِ جُدَدٌۢ بِيضٌ وَحُمْرٌ مُّخْتَلِفٌ أَلْوَٰنُهَا وَغَرَابِيبُ سُودٌ

a-lam tara annā allāha anzala mina l-samāʾi māʾan fa-akhrajnā bihi thamarātin mukhtalifan alwānuhā wa-mina l-jibāli judadun bīḍun wa-ḥumrun mukhtalifun alwānuhā wa-gharābību sūdun

Seest thou not that Allah sends down rain from the sky? With it We then bring out produce of various colours. And in the mountains are tracts white and red, of various shades of colour, and black intense in hue.

كَأَنَّهُمْ حُمُرٌ مُّسْتَنفِرَةٌ

ka-annahum ḥumurun mustanfiratun

As if they were affrighted asses,
