The second letter of His Eminence (a.s.) was received by Shaykh Mufeed (a.r) on 23 Zilhajj 412 A.H. It is as follows:
In the name of Allah, the Beneficent, the Merciful.
Peace and mercy of Allah (SwT) be upon you, O helper of religion. O one who invites to Allah (SwT) with the word of truth. We thank Allah (SwT), except Whom there is no deity, for your existence and invoke His blessings for our master and chief, Muhammad (S), the seal of the prophets and his Ahlul Bayt (a.s.). The letter inter alia says:
O sincere friend and struggler, may Allah (SwT) help you as He had helped His chosen servants in the past. I promise that if anyone from your brothers in faith acquires the fear of Allah (SwT) and pays that amount which is obligatory on him to the eligible recipient, would be safe from sorrow and calamities. But if anyone is miserly in giving away the wealth that Allah has given him temporarily he has made a loss for his children and his hereafter.
This letter written on the 1st of Shawwal in 412 A.H. by His Eminence (a.s.) contains the following in the end:
This is my letter to you; O friend the truth is inspired upon you. Keep it secret from everyone and only convey the points mentioned in it to those of our friends whom you trust. If Allah (SwT) wills, the blessings of Allah (SwT) would be in their share. Praise be to Allah (SwT) and blessings be upon our chief Muhammad (S), the Prophet and his purified Progeny.6
This letter contains some remarkable points:
In this letter, His Eminence, the Master of the Age (a.s.) has addressed Shaykh Mufeed as the helper of truth and the caller to Allah (SwT) with truth, which are some of the loftiest qualities of righteous people.
In this letter he has announced that his Shias should recite the supplication for the safety and release of His Eminence (a.s.) from oppressors and nothing would come in between the supplication from reaching the Almighty.
In this letter, His Eminence (a.s.) has commanded his Shias to observe piety and to keep away from disobedience of Allah (SwT). They must pay up their religious taxes. In the same way they should cultivate fear of Allah (SwT) and obey Allah (SwT) in the true sense. If they do thus no barrier would remain between them and His Eminence (a.s.) and they shall be endowed with the good fortune of seeing the Imam (a.s.). But their sins are barriers between the Shias and His Eminence (a.s.) and they do not allow them to have the honor of meeting the Imam.
