Surah 12. Yusuf, Ayah 47

Joseph not only shows what will happen, but, unasked, suggests the measures to be taken for dealing with the calamity when it comes. There will be seven years of abundant harvest. With diligent cultivation they should get bumper crops. Of them they should take a little for their sustenance and store the rest in the ear, the better to preserve it from the pests that attack corn-heaps when they have passed through the threshing floor.
