There is a narration from Sa’d who said:” “There are three traits that if one of them were in me, it was more beloved to me than the world and whatever is in it.”
“I heard the Messenger of Allah (ص) say to Ali (ع): “Your rank in relation to me is the same as Aaron's relation to Moses except that there is no Prophet after me.”
And I heard him say (on the day of triumph of Khaibar): “Tomorrow I will hand over the banner of war to a man who loves Allah and the Messenger, and Allah and His Messenger love him, and he will never turn his back on the enemy or flee.”
And I heard him say: "Whosoever I am his master, Ali is his master."
