182. Kitāb Man lā Yahdurhu al-Faqih, narrating from Marāzim ibn Hakim al-Azdi narrating from Imām al-Sādiq (a.s.) who said concerning a boy who is being circumcised: “He [the father] should say: “O Allah! This is Your way and the way of Your Prophet, may Your praises be upon him and his progeny, and it is our obedience to You and Your Prophet, by Your wish, Your will and Your decree for an order that You have commanded, a decree You have made certain, and a command You have affirmed. So, I made him taste the hotness [pain] of iron in his circumcision and shedding of blood for a reason You know more than I. O Allah! Purify him from sins, prolong his lifespan, keep away sicknesses and pains from his body, add to his wealth and repel poverty from him, for surely You know and we do not know.”
Then Abu ‘Abdullah [al-Sādiq] (a.s.) said: “Any man who does not recite this at the time of his son’s circumcision should recite it before he reaches puberty, and if he recites it, he will be safeguarded from being killed or harmed by the iron.”1
183. al-Kāfi, narrating from ‘Ali ibn Yaqtin who said: “I asked Abu al-Hasan [al-Kāzim] (a.s.) about the circumcising of a boy on the seventh day [of his birth], and if it is a Sunnah or can it be postponed?, and which one is better?”
He (a.s.) said: “It is of the Sunnah on the seventh day, and it does not matter if it is delayed.”2
