On the seventh of Muharram 61 AH, Imam al-Hussayn (peace be upon him) was prevented of water.

On the seventh day of Muharram in 61 AH, Omar Ibn Sa'd (may God curse him) entrusted five hundred men to guard the al-'Alaqmi River, after he received a letter from Ibn Ziyad ordering him to prevent water from al-Hussayn (peace be upon him), his family and companions (may Allah be pleased with them).
On the same day, Imam al-Hussayn (peace be upon him) met with Omar Ibn Sa'd, to try to convince him from fighting Ahl al-Bayt (peace be upon them), but Ibn Sa'd did not accept. So, Imam al-Hussayn (peace be upon him) told him: "May Allah slaughter you on your bed soon, and not forgive you on judgment day. I swear to Allah I wish you not let you eat from the grist of Iraq only few. Then Ibn Sa'ad said sarcastically: 'barley more adequacy than grist".
