Quran 2:247 — The Heifer (Al-Baqarah)

Their prophet said to them, "GOD has appointed Taloot (Saul) to be your king." They said, "How can he have kingship over us when we are more worthy of kingship than he; he is not even rich?" He said, "GOD has chosen him over you, and has blessed him with an abundance in knowledge and in body." GOD grants His kingship to whomever He wills. GOD is Bounteous, Omniscient.

[2:246] Have you noted the leaders of Israel after Moses? They said to their prophet, "If you appoint a king to lead us, we will fight in the cause of GOD." He said, "Is it your intention that, if fighting is decreed for you, you will not fight?" They said, "Why should we not fight in the cause of GOD, when we have been deprived of our homes, and our children?" Yet, when fighting was decreed for them, they turned away, except a few. GOD is aware of the transgressors.

[2:248] Their prophet said to them, "The sign of his kingship is that the Ark of the Covenant will be restored to you, bringing assurances from your Lord, and relics left by the people of Moses and the people of Aaron. It will be carried by the angels. This should be a convincing sign for you, if you are really believers."
