58. Good land produces vegetation in abundance, by Allah’s permission. Likewise, the believer understands the teachings they are given and they benefit from them, acting accordingly with righteousness. On the other hand, the rotten, salty land only produces vegetation in small amounts, and there is little goodness in what it produces. Likewise, the disbeliever will not benefit from the true teachings they receive, and will not perform good actions that benefit him. Through such variation Allah reveals His signs and proofs in different ways, to confirm the truth to a people who are thankful for Allah’s blessings, who do not disbelieve them, and who follow their Lord.
