Quran 2:132 — The Heifer (Al-Baqarah)

Moreover, Abraham exhorted his children to do the same, and so did Jacob: "O my children, GOD has pointed out the religion for you; do not die except as submitters."

[2:131] When his Lord said to him, "Submit," he said, "I submit to the Lord of the universe."

[2:133] Had you witnessed Jacob on his death bed; he said to his children, "What will you worship after I die?" They said, "We will worship your god; the god of your fathers Abraham, Ismail, and Isaac; the one god. To Him we are submitters."
