The Prophet (may Allah's peace and blessings be upon him) likens the divine guidance and knowledge that were revealed to him to heavy rain that fell on land. The land was of three kinds. Some spots were good enough to absorb water and grow plants, so the people made use of them; other spots did not grow plants but served as containers of water, so the people made use of the water by drinking, watering their animals, and irrigating their plants; and further spots neither held water nor produced plants. Likewise, people receive what Allah sent the Prophet (may Allah's peace and blessings be upon him) with of knowledge and guidance in different ways. Some of them understand the religion, so they learn and teach others. These are useful to themselves and to others. Other people carry knowledge without having insight into it, so they benefit others but do not profit themselves. And yet other people do not pay any heed to what the Prophet (may Allah's peace and blessings be upon him) came with of knowledge and guidance, and they turn away from it and disregard it. So they neither profit from what the Prophet (may Allah's peace and blessings be upon him) came with nor benefit others.
