Al-Musayyab bin Najabah said: Sayyiduna Ali (may Allah be pleased with him) said: "Shall I not tell you about my own close ones and my household?" We said: Certainly. He said: "As for Hasan, he is a man of the dining spread and the food bowl, a young man among young men; and if the two rings of the saddle girth were to meet (i.e. if the battle became fierce), he would be of no use to you in war, not even as much as a sparrow's snare. As for Abdullah bin Ja'far, he is a man of amusement, ease and idle things; and do not let the two sons of Abbas deceive you. As for me and Husayn, I am who I am and Husayn is who he is: we are from you and you are from us. By Allah! I fear that these people will be made to prevail over you because of their righteousness in their land and your corruption in your land, because of their fulfilment of trust and your betrayal, because of their obedience to their leader and your disobedience to him, and because of their unity upon their falsehood and your division upon your truth; until their rule becomes long, until they do not leave anything Allah has made sacred without making it lawful, and there remains no house of clay or tent of hair but their oppression enters it; until each of you becomes their follower, and until one of you supports them the way a slave supports his master: when he is present he obeys him, and when he is absent he curses him; and until the wealthiest of you will be the one with the best opinion of Allah. So if Allah grants you well-being, accept it, and if you are tested, be patient, for the final outcome belongs to the God-fearing."
