Ibn Hibban

The Noble Prophet (peace and blessings be upon him) also said: “The example of the guidance and knowledge that Allah Almighty has bestowed upon me is like rain that falls on a land. Some part of that land is pure; it accepts the water and produces abundant grass and fodder, or it retains the water, and Allah Almighty benefits people through it—they drink from it themselves, give it to their animals, and use it for cultivation. This rain also falls on another part of the land, which is a barren plain; it neither retains the water nor grows any grass. This is the example of the person who attains understanding of Allah’s religion, and Allah Almighty benefits him through what I have been sent with—he acquires knowledge and acts upon it. And this is the example of the person who does not raise his head for it (i.e., does not pay attention to it) and does not accept the guidance of Allah with which I have been sent.”
