It is narrated from Hazrat Bishr bin Ghalib that Abdullah bin Zubair met Hazrat Hussain bin Ali (may Allah be pleased with him) in Makkah Mukarramah. Hazrat Abdullah asked, "O Abu Abdullah, I have heard that you intend to go to Iraq." He replied, "Yes." Hazrat Abdullah said, "Do not do so, for indeed they are the killers of your father and the ones who struck your brother's abdomen with a spear. If you go to them, they will kill you."
