If mountains understood some of that which was in this book, they would crack and split because of the fear of Allah, and turn back to the obedience of Allah. Do whatever you like*(so Allah will see your work and (so will) His Messenger and the believers; and you shall be brought back to the Knower of the unseen and the seen, then He will inform you of what you did)* .[^106] Praise be to Allah, the Lord of the worlds, and His blessings be on Muhammad and all his progeny.”[^107] 2.

His letter to the people of Qum and Aabeh Imam Abu Muhammad (a.s.) sent a letter, some parts of which were lost, to his Shia from the people of Qum and Abeh (Aveh) saying to them, “Allah the Almighty with His generosity and kindness has favored His people with His prophet Muhammad (a.s.) as a bearer of good tidings and a warner, and has made you succeed in accepting His religion, granted you with His guidance, and planted into the hearts of your past ancestors (may He have mercy on them) and your living offspring (may He suffice and make them live long) the love of the pure progeny (of the Prophet).

They, who had left, left on the way of righteousness, and the path of truth and success, and they went to the place of successors, got the fruits of what they had sowed, and found the result of what they had done before… Our intention is still firm, and our selves are satisfied with your good thoughts. The fixed relation between us and you are firm. It is a will that our ancestors and your ancestors had recommended, and a covenant that had been entrusted to our youth and your old men.

They are still on their faith, and Allah has gathered us in the close relation, and close kinship. The Alim (peace of Allah be on him) said, ‘A faithful is a brother of a faithful from his father and mother…”[^108] 3. His letter to Ali bin al-Husayn Imam Abu Muhammad (a.s.) sent a letter to the famous jurisprudent Abul Hasan Ali bin al-Husayn bin Musa bin Babwayh al-Qummi, the notable of the Shia and prominent personality in Hadith, jurisprudence, and the rest of the Islamic sciences.

Imam Abu Muhammad (a.s.) said in his letter, “Praise be to Allah the Lord of the worlds, and the end is for the righteous, the Paradise is for the monotheists, the Hell is for the atheists, and there should be no hostility except against oppressors, and there is no god but Allah the best of creators, and blessing be on the best of His creation Muhammad and his pure progeny.
