The Cow - Al-Baqara

And certainly you have known those among you who exceeded the limits of the Sabbath, so We said to them: Be (as) apes, despised and hated.

So We made them an example to those who witnessed it and those who came after it, and an admonition to those who guard (against evil).

And when Musa said to his people: Surely Allah commands you that you should sacrifice a cow; they said: Do you ridicule us? He said: I seek the protection of Allah from being one of the ignorant.

They said: Call on your Lord for our sake to make it plain to us what she is. Musa said: He says, Surely she is a cow neither advanced in age nor too young, of middle age between that (and this); do therefore what you are commanded.

They said: Call on your Lord for our sake to make it plain to us what her color is. Musa said: He says, Surely she is a yellow cow; her color is intensely yellow, giving delight to the beholders.

They said: Call on your Lord for our sake to make it plain to us what she is, for surely to us the cows are all alike, and if Allah please we shall surely be guided aright.

Musa said: He says, Surely she is a cow not made submissive that she should plough the land, nor does she irrigate the tilth; sound, without a blemish in her. They said: Now you have brought the truth; so they sacrificed her, though they had not the mind to do (it).

And when you killed a man, then you disagreed with respect to that, and Allah was to bring forth that which you were going to hide.
