Wool

And Allāh has made for you from your homes a place of rest and made for you from the hides of the animals tents which you find light on your day of travel and your day of encampment; and from their wool, fur and hair is furnishing and enjoyment [i.e., provision] for a time.

On the Day the sky will be like murky oil,¹

And the mountains will be like wool,¹

It is the Day when people will be like moths, dispersed,¹

And the mountains will be like wool, fluffed up.¹
