O , göydən su endirir və vadilər ölçülərinə uyğun öz məcralarından daşaraq sel olub axır . Sel də üzə çıxmış bir köpüyü götürüb aparır .
He sends down water ( rain ) from the sky , and the valleys flow according to their measure , but the flood bears away the foam that mounts up to the surface , and ( also ) from that ( ore ) which they heat in the fire in order to make ornaments or utensils , rises a foam like unto it , thus does Allah ( by parables ) show forth truth and falsehood .
