Mujahid narrates that Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said to me: "Had I not heard that you are like us, the People of the House, I would not have narrated this hadith to you." Mujahid said: "It will remain a secret; I will not tell it to anyone whom you dislike." Ibn Abbas (may Allah be pleased with them both) said: "From us, the People of the House, there will be four (special figures): from us will be al-Saffah, from us al-Mundhir, from us al-Mansur and from us al-Mahdi." Mujahid says: I said to him: "Explain these four to me." He said: "As for al-Saffah, he will at times kill his supporters and pardon his enemy. As for al-Mundhir, he will give so much wealth that he will not consider it great in his heart, and he will withhold only a small portion of his own right. As for al-Mansur, he will be granted such victory and help over his enemy as will be half of the help given to the Messenger of Allah (peace and blessings be upon him); his (peace and blessings be upon him) enemy was struck with awe at a distance of two months' journey, while the enemy of al-Mansur will be struck with awe at a distance of one month's journey. And as for al-Mahdi, he will fill the earth with justice and fairness just as it will have been filled with oppression and injustice; grazing animals will be safe from beasts of prey, and the earth will cast out the pieces of its liver." Mujahid says: I asked: "What is meant by the pieces of its liver?" He said: "(Treasures) like pillars of gold and silver." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
