(Qur’an...
(Qur’an, Surah Hadid 57:11) The Imam said: It is revealed about doing favor to the Imam.[^3] And through the author’s own chain of narrators it is narrated from Hasan bin Miyah from his father that he said: His Eminence, Abu Abdullah Imam Sadiq (as) said to me: O Miyah, one dirham spent in doing favor to the Imam is heavier than Mt. Uhad.
(Qur’an, Surah Raad 13:21) The Imam said: It was revealed with regard to the relationship of Aale Muhammad (as) and it is also about your relatives. Then he said: Do not be of those who take only one meaning.[^6] In a reliable traditional report it is narrated from His Eminence (aj) that he said: I take one dirham from one of you while I am one of the richest man of Medina, the sole aim of this is that you may be purified.
(9:103) In Man Laa Yahzarul Faqih it is mentioned in the Chapter of doing good to Imam (as) that Imam Ja’far Sadiq (as) was asked regarding the following verse: مَنْ ذَا الَّذِي يُقْرِضُ اللَّهَ قَرْضًا حَسَنًا Who is there that will offer to Allah a good loan…(2:245) He (as) said: It is with reference to kindness to the Imam. He also said: One dirham spent as kindness to the Imam is better than a million dirhams spent in some other charitable act.
In the same book it is mentioned in the Chapter of the virtues of Hajj: One dirham spent in Hajj expenses is better than a million dirhams spent in some other good way, one dirham that reaches the Imam is equal to spending a million dirhams in Hajj expenses.
