It is narrated in Museerul Ehzan, that it is related to me, that Malik bin Anas said, that I saw Ubaydullah hitting at the teeth of Husayn (a.s.) with his cane and saying, “What good teeth you possess O Husayn”! I said, “By Allah! I consider the conclusion to be evil. I have seen the Prophet of Allah (S) kissing the place where you hit your cane”.
Sa’eed bin Ma’az and Umar bin Sahl were also present when Ubaydullah was hitting at the eyes and nose of Husayn (a.s.) and was entering it into his blessed mouth. Azdi says that Sulayman bin Rashid relates from Hameed bin Muslim, that Umar bin Sa’ad called upon me and dispatched me to his family with glad tidings of his victory and safety. I came to his family and delivered his message to them.
Then I came out and entered the royal palace and saw that (Ubaydullah) Ibn Ziyad had called for an assembly. Groups started visiting him and he had given them an audience. He had permitted men to visit him and I too entered therein along with others. I saw that the head of Imam Husayn (a.s.) was kept near him and he was striking at his teeth with the cane of his hand for an hour.
When Zayd bin Arqam saw that he was not withholding his hand, he called out, “Lift your cane off these teeth, for by Allah, besides Whom there is no Deity, I have seen both the lips of the Prophet of Allah (S) upon them kissing”, saying this the old man’s rancor erupted and he started weeping. Ibn Ziyad said, “May your Lord make you weep! By Allah! Had you not been old or turned stupid and your intellect having parted, I would have blown your head off”. Then he arose and left.
When I came out of the royal palace, I saw people saying to one another, “By Allah! Zayd bin Arqam uttered such words which if the son of Ziyad would have heard it, he would have killed him”. I asked them as to what he had said. They replied, “He said: A slave obtained a slave, and considers all men to be the sons of his slaves (An Arabic proverb). O Arabs! From today on you have become slaves. You killed the son of Fatemah (a.s.) and made the son of Marjanah your commander.
He kills the virtuous amongst you, and know that he has made you his slaves. You have put yourselves in humiliation, and death be upon those whose put themselves in humiliation. ” It is related in Tazkiratul Khawas of Sibt Ibn Jawzee, and Sawaeqe Muhriqa, as also in Tabarul Mazab, that Zayd bin Arqam arose and said, “O people! From today on you have become slaves.
