Whatever he would drink he would vomit
A similar incident is written by Imam Ibn Atheer in Al Kaamil Fit Tareekh:
Translation: ‘Abdullah bin Abil Haseen shouted: O Hussain! Do you not see water? You will be martyred thirsty, but you will not get to taste a single drop of water. Imam Hussain (May Allah be well pleased with him) said: O Allah! Kill him thirsty and don’t forgive him.
After this, that person fell ill. He would drink a small quantity of water and vomit it out. He would again drink water but his thirst wouldn’t be quenched. He would drink and vomit it out. This was his condition until he died. (Al Kaamil Fit Tareekh, Vol. 167)
He had taunted Imam Hussain (May Allah be well pleased with him) with the words: You will not get to taste a single drop of water. His end was so shocking that he would take a sip of water and vomit it out, as if water itself wouldn’t want to stay in his stomach.
