Tradition 15
Through successive chain of transmitters, Shaikh Sadooq relates from Ibne Masroor, from Ibne Amir, from his uncle, from Ibrahim bin Abi Mahmood, who says that Imam Ali ar Reza (a.s) said,
"Moharram is a month in which bloodshed was considered unlawful by the pre-Islamic pagan Arabs, but our blood was shed in this month. Our sanctity was violated and our children & women-folk were made captives. Our tents were set ablaze and whatever was found therein was looted. And they did not even honour the relation, which we share with the Prophet of Allah (s.a.w.s). The day on which Imam Husain (a.s) was martyred has injured our eyes and our tears are constantly flowing since then. Our dear ones were dishonoured on the plains of grief and trials (Karbo bala) making way for sorrows and sufferings until Qiyamah. Thus, sorrowful people should mourn over it (the martyrdom of Imam Husain), for weeping upon it nullifies the major sins."
Then he said,
"When the month of Moharram would approach, no one would see my father (Imam Moosa al Kazim) ever laughing until the tenth, and grief would prevail upon him. And the tenth would be the day of sorrow, grief and lamenting, and he would say: This is the day when Husain (a.s) was massacred."
