An early Meccan sura in which God swears by the warhorses that He has subjected to men's use that man is ungrateful and misguided.
In the name of God, the Lord of Mercy, the Giver of Mercy
By the charging steeds that pant and strike sparks with their hooves, who make dawn raids, raising a cloud of dust, and plunging into the midst of the enemy, man is ungrateful to his Lord- and He is witness to this- he is trul excessive in his love of wealth.
Does he not know that when the content of graves burst forth, when the secrets of hearts are uncovered, on that Day, their Lord will be fully aware of them all?
*two suras about wealth, now. i asked the same question of the Christians, so: what do Muslims believe to be a moderate love of wealth?
