3:103 And hold fast to the Bond of Allah, together, and do not scatter. Remember the Favor of Allah bestowed upon you when you were enemies, and how He united your hearts, so that by His Favor you became brothers. And how He saved you from the Pit of Fire when you were on the brink of it. And so Allah makes plain to you His verses, in order that you will be guided.
3:105 Do not follow the example of those who became divided and differed with one another after clear proofs had come to them. For those, there is a great punishment.
