One of the students of the Imam took upon himself the responsibility of publishing the book “Makasib-e Muharramah” (Illicit earnings). At the end of the book the Imam had not written his own name. When he was told to write the name of the author of the book, he stated: “Not at all! It is not necessary. The contents are important.” I pleaded with him but he did not agree and finally stated: “It is not necessary. If it is to be printed in this way, well and good otherwise let it not be printed.” Finally, I hit upon an idea and requested him to at least write his name in the book so that those who have any questions will know whom to refer it to and it becomes evident who has written it. He stated: “Well, if this is the case, I will write.” He wrote: “This book been written with the hand of a mortal by the name of Ruhullah al-Musawi al-Khomeini.”
Written with the hand of a mortal: Ayatullah Mas‘udi Khomeini
