Ja`far b. Muhammad b. Masrur narrated to us. He said: al-Husayn b. Muhammad b. `Amer narrated to us from his uncle `Abdullah b. `Amer from Ibrahim b. Abi Mahmud. He said:

al-Rida said: Muharram is the month in which the people of the Jahiliyya would prohibit fighting, but our blood was deemed lawful in it, our sanctity was violated in it, our offspring and our women were made captives in it, fire was ignited in our marquees and what was in them of our provision was plundered. And (despite our relationship) to the Messenger of Allah (s), the sanctity in our affair was not observed. Surely, on the day of Husayn, our eyelids were wounded, our tears made to flow, our beloved abased in the land of suffering and affliction. Suffering and affliction were rained down on us. So, those who lament should lament on the like of Husain till the day of termination (i.e. the last day of this world), for surely the crying diminishes the great sins. Then, he said: When the month of Muharram would enter, my father would not be seen laughing, and intense grief would overcome him until ten days had passed from it. So, when it would be the tenth day, that day would be the day of his affliction and his mourning and his lamenting. And he would say: This is the day on which Husayn was killed.
