Moses said to them: "Indeed, Allah says: it is a cow not trained for work in plowing the earth for agriculture, nor prepared for irrigation from the waterwheel, and free from all blemishes, and there is no mark of a color in it other than the color of its skin." They said: "Now you have come with the true description of the cow," so they were forced to sacrifice it after long evasion, and they almost did not do that due to their stubbornness. And thus they made it difficult, so Allah made it difficult for them.
