4. He said: Abul Hasan ‘Ali ibn Muhammad al-Katib reported to me from al-Hasan ibn Abdul Karim al-Za’farani, who reported from Abu Ishaq ibn Muhammad al-Thaqafi, who reported from Ja’far ibn Muhammad al-Warraq, who reported from Abdullah ibn al-Azraq al-Shaybani, who reported from Abu al-Jahhaf, from Mu’awiyah ibn Tha’labah who said: When Mu’awiyah found himself fully entrenched in his rule, he sent Busr ibn Artat to Hejaz, to hunt for the Shi’ahs of ‘Ali ibn Abi Talib, peace be upon him. At that time, Ubaidullah ibn al-Abbas governed Makkah. He (i.e. Busr) summoned him, but could not find him. Then he was informed that Ubaidullah had two infant sons. So he set out to reach them, and when he found them - they had two (tender) forelocks (shining) like pearls - he ordered to kill them. When their mother came to know this, her grief put her on the verge of death. At that moment, she said: "Ah! Who has heard about my two dear sons, who were like two pearls torn from their oyster! Ah! Who has known about my two dear sons, who are my ears, my eyes! My heart today feels wrenched. I am informed that Busr (did it), but I cannot believe what they thought (of us) from (what I hear about) their speech and the falsehood they contrived. So the sharp sword fell on the throat of my two little ones, that indeed is tyranny and immoderation, Who showed love to the two tormented infants who had lost their progenitor." He said: Then once Ubaidullah ibn al-Abbas met Mu’awiyah while Busr ibn Artat was present. Mu’awiyah said: "Do you recognize this old man who killed the two infants?" Busr said: "Yes, I killed them, so what?" Then Ubaidullah said: "I wish I had a sword." Busr said: "Here is my sword," pointing to his own sword. Mo’awiya scolded him saying: "Woe unto you! What makes you a fool in spite of your old age! You trust a man whose two sons you killed, and give him your sword? Perhaps you do not know the courage of Banu Hashim? By Allah, if you gave it to him, he could kill you first, and then I would be the next." Ubaidullah said: "On the contrary, by Allah, I would begin with you (O Mu’awiyah) and he (i.e. Busr) would be the next."
