Quran 2:70 — The Heifer (Al-Baqarah)

They said, "Call upon your Lord to show us which one. The heifers look alike to us and, GOD willing, we will be guided."

[2:69] They said, "Call upon your Lord to show us her color." He said, "He says that she is a yellow heifer, bright colored, pleases the beholders."

[2:71] He said, "He says that she is a heifer that was never humiliated in plowing the land or watering the crops; free from any blemish." They said, "Now you have brought the truth." They finally sacrificed her, after this lengthy reluctance.
