Overall meaning : Allah, Exalted be He, declares that it is He who sends forth the winds, bearing glad tidings of rain with which He shows mercy towards His creation; and when they have gathered heavy rain-laden clouds, He drives them on to some dead land and sends down water to it, and thereby brings forth fruits of every kind. Just as He brings a dead land back to life with water, He points out, so, too, He will bring forth people from their graves alive, so that with such explanation, people may think and reflect and realize His power to resurrect the dead.
The good, pure land, He then states, whose soil is fertile (like the case of the believer who benefits from His revelations and signs) yields good produce swiftly, by His permission; as for the land with poor, infertile soil (like the case of the unbeliever who does not benefit from His revelations and signs), its produce comes forth slowly and with difficulty and is devoid of all benefit, goodness and blessing. Just as He expounds His signs and proofs attesting to His Lordship and power to resurrect the dead, among other things, in diverse forms, so, too, He sets signs out and expounds them in various ways to prove the truth to people who give thanks to Him for His many blessings and show obedience to Him.
