You have been a man of ease and a profligate.
You have been a man of ease and a profligate. Then fight the man (Imam Husayn) and use violence against him and do not yield to any of his requests until his submits to my command.” It is related in Tareekh of Tabari that Azdi said, that Haris bin Hasirah relates from Abdullah bin Shareek Amiri, that when Shimr had got the letter written, he arose along with Abdullah bin Abi Mahl, who was an uncle of Ummul Baneen (a.s.), daughter of Hizam bin Khalid, and the wife of the Commander of the faithful Imam Ali bin Abi Talib (a.s.).
Ummul Baneen had four sons from Imam Ali (a.s.), viz. Abbas, Abdullah, Ja’far and Usman. Thus Abdullah bin Abi Mahl bin Hizam bin Khalid bin Rabi’ah bin Waheed bin Ka’ab bin Amir bin Kilab said, “May Allah rectify (the affairs for) the chief! Our nephews are along with Husayn, then if you deem fit, write down a document of security for them.” Ubaydullah said, “Very well”, then he ordered his scribe to write down the document of security for them.
Abdullah sent the letter to Karbala with one of his retainer named Kirman with the message that, “Your uncle (Abdullah bin Abi Mahl) has sent this document of security for you.” The youth replied, “Convey our greetings to our uncle and tell him that we are in no need of his security. Verily Allah’s security is better than that of the son of Sumayyah.” Shimr brought the letter of Ubaydullah to Umar bin Sa’ad. When Umar read it he said, “Woe be upon you! What have you brought?
May your house be ruined! May it be evil whatever you have brought me! By Allah! I know that you must have prevented him from doing that what I had written to him. And you have spoilt the matter, which could result in peace. By Allah! Husayn will not submit, for he has a noble soul.” Shimr said, “So now tell me, what do you intend doing? Will you obey the orders of the chief and fight his enemy?
If not, then hand over the charge to me.” Umar replied, “No, you shall not have this honor and you shall not get this position. I myself shall undertake this task and you shall be the commander of the foot soldiers.” Thus Umar bin Sa’ad proceeded towards Imam Husayn (a.s.) on Thursday the night of the ninth of Muharram with his army.
Proposal of security to Abbas bin Ali (a.s.) Shimr came and stood facing the companions of Imam Husayn (a.s.) and called out it a loud voice, “Where are the sons of our sister (of clan)”? Hearing this Hazrat Abbas, Abdullah, Ja’far and Usman came out and asked him as to what he desired.
