Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
Or were you witnesses when death approached Jacob, when he said to his sons, "What will you worship after me?" They said, "We will worship your God and the God of your fathers, Abraham and Ishmael and Isaac - one God. And we are Muslims [in submission] to Him."
Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allāh?" And who is more unjust than one who conceals a testimony he has from Allāh? And Allāh is not unaware of what you do.
He said, "You will not receive food that is provided to you except that I will inform you of its interpretation before it comes to you. That is from what my Lord has taught me. Indeed, I have left the religion of a people who do not believe in Allāh, and they, in the Hereafter, are disbelievers.
