Ashura and al-Husayn's words

Muhammad ibn Bakran al-Naqqash in the Kufa Mosque and Muhammad ibn Ibrahim ibn Ishaq al-Mokattib in Ray - may God be pleased with him - narrated that Ahmad ibn Muhammad ibn Sa’eed al-Hamadani - a servant of the Hashemites - quoted on the authority of Ali ibn Al-Hassan ibn Ali ibn Fadhdhal, on the authority of his father that Abil Hassan Ali ibn Musa Al-Reza (s) said, 
“God will provide for the needs of this world and the Hereafter of whoever does not try to provide for his needs on the Day of Ashura. The Honorable the Exalted God will make the Resurrection Day a day of pleasure and happiness for whoever makes the Day of Ashura his day of calamity, mourning, sorrow and crying. If one considers the Day of Ashura to be a blessed day for him and hoards things up in his house on that day, whatever he hoards up will not be blessed. He will be resurrected along with Yazid, Ubaydillah ibn Ziyad and Umar ibn Sa’d - may God damn them - on the Resurrection Day.”

Imam Al-Hussein (as) on his way to Karbala said:          
This world has changed, snubbed, and its good has turned tail. Nothing has remained from it except a thing that is as scanty as the leftover of a cup and a mean life that is like a noxious grazing. Have you not noticed that the right is ignored and the evil is not forbidden? This is sufficient for making the believers desire for meeting God rightfully. I consider death as happiness and life with the wrongdoers as boredom. People are certainly the slaves of this world. The religion is only a slaver on their tongues. They turn it wherever their livelihood demands. If they are examined by misfortunes, the religious will be very little.

Imam Redha (A.S.) said: 

With the advent of the month of Muharram, my father Imam Kadhim (A.S.) would never be seen laughing; gloom and sadness would overcome him for (the first) ten days of the month; and when the tenth day of the month would dawn, it would be a day of tragedy, grief and weeping for him.
