Do you have an exegesis or interpretation of the hadith: "A man will emerge from beyond the river, called Al-Harith ibn Harrath, with a man named Mansour at his vanguard. He will pave the way – or enable – for the family of Muhammad just as Quraish paved the way for the Messenger of Allah, peace and blessings be upon him. It is incumbent upon every believer to support him – or he said, to respond to him"?

The Hadith is weak, and Al-Mundhiri and others have judged it as such. Its meaning is that it is an announcement of the emergence of a man whose name is so-and-so, and at the vanguard of his army is a man called Mansour. This man prepares the means with money and weapons for the caliphate and strengthens it with his army. The reference in his saying "for the family of Muhammad" is to the Mahdi. Since the Hadith is weak, no rulings can be built upon it.
