163. I have sent revelation to you, O Messenger, as I had sent revelation to the prophets before you. This revelation to you is not something strange or unexpected. I had sent revelation to Noah and to the prophets who came after him. I sent revelation to Abraham and his two sons, Ishmael and Isaac, and to Jacob, the son of Isaac, and to the Tribes (which refers to the prophets that were from the twelve tribes of the Israelites from the children of Jacob). I also gave David a book called the Psalms.
