I heard Imam Ali ibn Musa Ar-Ridha (as), say: "'When the head of Imam Hussain ibn Ali (as), peace be upon him, was taken to Sham, Yazid - may Allah (swt) curse him - ordered that it be placed and a table was set upon it. He (Yazid) and his companions came forward, eating and drinking fermented beverages. When they finished, he ordered the head to be placed in a basin under his couch, and a chessboard was spread over it. Then Yazid - may Allah (swt) curse him - sat playing chess while mentioning Imam Hussain ibn Ali (as) and his father (as) and grandfather (sw), peace be upon them, mocking their remembrance. Whenever he gambled with his companion, he would take the fermented beverage and drink it three times, then pour the remainder onto the ground near the basin.' Imam (as) continued: 'Whoever is from our Shia should abstain from drinking fermented beverages and playing chess. And whoever looks at fermented beverages or at chess should remember Imam Hussain ibn Ali (as), and curse Yazid and the family of Ziyad. By doing so, Allah (swt), the Mighty and Majestic, will erase his sins, even if they are as numerous as the stars.
