Shiavault - a Vault of Shia Islamic Books Nafasul Mahmum, Relating to the heart rending tragedy of Karbala' Imam Husayn (a.s.) in Karbala’ It is written in Biharul Anwar, that Ubaydullah bin Ziyad kept dispatching troops one after the other to Umar bin Sa’ad (in Karbala) until he had thirty thousand horsemen and foot-soldiers with him. Then Ubaydullah wrote to Umar: “I have not left any excuse for you with respect to the (quantity of) army.
Then remember to inform me, every morning and evening, about your affairs.” Ubaydullah had started inciting Umar (for battle) from the sixth of Muharram. Habib bin Mazahir came to Imam Husayn (a.s.) and told him, “O son of the Prophet of Allah (S)! Nearby there is a branch of the tribe of Bani Asad.
If you permit, I shall go to them and invite them to assist you, perhaps Allah will defend you through them.” Imam gave him permission and Habib, in the darkness of the night, disguised himself and went towards them. They recognized him and inquired from him as to what he desired. Habib replied, “I have brought the best gift for you. I have come to you to invite you to assist the grandson of our Prophet.
He is here with a group of believers, each one of whom is better than a thousand men, and they shall not leave him, betray him nor surrender him (to the enemies). Then Umar bin Sa’ad has surrounded them, you are my tribesmen, hence I invite you towards welfare. Then today pay heed to my words and assist him, so as to gain honor in this world as well as the Hereafter. I swear by Allah!
Whoever among you is martyred in the way of Allah along with the grandson of the Prophet of Allah, then he will be in the lofty station among the friends of Muhammad (s.a.w.s).” Hearing this a man from among them, named Ubaydullah bin Basheer arose, and said, “I am the first one to accept this invitation.” Then he recited the following Rajaz: “The nation knows that when the horsemen are ready to fight, I stand as a warrior, valorous, similar to a forest Lion.” Then the men of the tribe gathered until ninety people prepared to go to assist Imam Husayn (a.s.).
At that moment, a man from among them went and apprised Umar bin Sa’ad about the situation and he sent Ibn Azraq with four hundred horsemen towards Bani Asad. When they (Bani Asad) were coming towards the army of Imam Husayn (a.s.), the horsemen of Umar bin Sa’ad stopped them on the bank of the river Euphrates. A quarrel started between them which turned into a fierce battle.
