The History of a Najashi

Ruhwa'n al-Zubair was the son of Azubair, al-li'Allah. He once said to Arimam Azuray: Allah did not take a bribe from me when he gave me back my kingdom,. So how can I take a bribe for my kingdom? And Allah did not do what they wanted him to do against me, so how can I do what they want me to do against him? This was the statement of a Najashi, and there's a history behind that statement.
