Muhammad ibn Ali Majiluwayh - may God be pleased with him -narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of his father, on the authority of al-Rayyan ibn Shabeeb,
“I went to see Al-Reza (s) on the first day of the (Arabic) month of Muharram.
The Imam (s) said, ‘O Ibn Shabeeb! Are you fasting?’
I answered, ‘No.’
The Imam (s) said, ‘Today is the day on which Zakariya prayed to his Lord - the Honorable the Exalted, ‘There did Zakariya pray to his Lord, saying, ‘O my Lord! Grant unto me from Thee a progeny that is pure: for Thou art He that heareth prayer!’’ [529 - Qur’an, 3:38]
And God fulfilled his prayer and ordered the angels to call Zakariya ‘While he was standing in prayer in the chamber, the angels called unto him, ‘(Allah) doth give thee glad tidings of Yahya, witnessing the truth of a Word from Allah, and (be besides) noble, chaste, and a Prophet, of the (goodly) company of the righteous.’’ [530 - Qur’an, 3:39]
Therefore, just as God fulfilled the prayers of Zakariya, the Honorable the Exalted God will fulfill the prayers of whoever fasts on this day, and asks God for something.’
The Imam (s) then added, ‘O Ibn Shabeeb! Muharram is the month in which the people of the Age of Ignorance had forbidden committing any oppression and fighting in. However, this nation did not recognize the honor of this month or the honor of their own Prophet (s).
In this month, they killed the Prophet’s offspring, they enslaved the women, and took their belongings as booty. God will never forgive them.
O Ibn Shabeeb! If you wish to cry, then cry for Al-Hussein ibn Ali ibn Abi Talib (s) who was slaughtered like a sheep, and was killed along with the members of his household.
Eighteen people were martyred along with Al-Hussein (s) who had no equal on Earth.
The seven heavens and the Earths mourned for his martyrdom.
Four thousand angels descended to the Earth to assist him (Imam Hussein) (s). However, Al-Hussein (s) was destined to be martyred. They will remain at his shrine with wrinkled hair until the Riser (Imam al-Mahdi) (s) rises. Then they will be among those who will assist him (s). Their slogan will be Ya li tharat Al-Hussein (Revenge for Al-Hussein’s blood!)
O Ibn Shabeeb! My father narrated that his father (s) quoted on the authority of his grandfather (s) that when they murdered my grandfather Al-Hussein (s), the heavens cried (dark) red blood and dirt.
O Ibn Shabeeb! If you cry for Al-Hussein (s) in such a way that tears flow down your cheeks, then God will forgive all the sins that you have committed whether they be minor or major, whether they be a few instances or a lot.
O Ibn Shabeeb! If you would like to meet the Honorable the Exalted God without having any sins then go to visit (the Shrine of) Al-Hussein (s).
O Ibn Shabeeb! If you would like to accompany the Prophet (s) in the rooms of Paradise, then damn the murderers of Al-Hussein (s).
O Ibn Shabeeb! If you would like to be rewarded just as those who were martyred along with Al-Hussein ibn Ali (s), whenever you remember Al-Hussein (s) say,
‘I wish I was with them and could achieve the great prosperity.’
يا لَيْتَنِي كُنْتُ مَعَهُمْ فَأَفُوزَ فَوْزاً عَظِيماً
O Ibn Shabeeb! If you would like to be in the same high ranks in Paradise with us, then be sad when we are sad and be happy when we are happy, and I advise you to have us since the Honorable the Exalted God will resurrect whoever even likes a rock with that same rock on the Resurrection Day.””
