Is 'The Cow' also mentioned in Quran? :|

yes it is longest verse of Kuran

a part from it

67. 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.

68. 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.

69. 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.

70. 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.

71. 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).

72. 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.

73. So We said: Strike the (dead body) with part of the (Sacrificed cow), thus Allah brings the dead to life, and He shows you His signs so that you may understand.

93. And when We made a covenant with you and raised the mountain over you: Take hold of what We have given you with firmness and be obedient. They said: We hear and disobey. And they were made to imbibe (the love of) the calf into their hearts on account of their unbelief Say: Evil is that which your belief bids you if you are believers.

well Azeris are considered Turkic peoples

Azeris are Turks like us. We have same ancestors, same history, same language but they are mostly Shias. (You should look chaldiran war which was among two turk states Battle of Chaldiran - Wikipedia, the free encyclopedia)In reality Azerbaijan is a place name like Anatolia. I think if we are not anatolians they are not azeris too, already nearly all of them accept that.
