Hadith.4725 - Abdullah ibn Ja'far al-Himyari wrote to Imam Abu Muhammad Al-Hasan ibn Ali (as), saying: "It has been narrated from the Righteous Ones (peace be upon them) that they said: 'Circumcise your children on the seventh day so they may be purified, for the earth complains to Allah (swt), the Mighty and Majestic, about the urine of the uncircumcised.' May Allah make me your ransom, but the barbers in our region are not skilled in this, and they do not circumcise on the seventh day. However, we have a barber who is a Jew. Is it permissible for the Jews to circumcise Muslim children or not?" Imam (as) replied: "On the seventh day - do not oppose the Sunnah, God willing."

Hadith.4726 - It was narrated from Murazim ibn Hakim Al-Azdi that Abu Abdullah (as) said regarding the circumcision of a child: "One should say: O Allah (swt), this is Your (swt) Sunnah and the Sunnah of Your Prophet (peace and blessings be upon him and his family), and it is our following of You (swt) and Your Prophet (sw) by Your (swt) will, Your (swt) desire, and Your (swt) decree for a matter You (swt) have willed, a decision You (swt) have made obligatory, and a command You (swt) have executed. You (swt) have made him taste the heat of iron in his circumcision and cupping for a matter You (swt) know better than I do. O Allah (swt), purify him from sins, increase his lifespan, protect his body from afflictions and his flesh from pain, increase him in wealth, and remove poverty from him. Indeed, You (swt) know while we do not." Abu Abdullah (as) also said: "Whoever does not say this at the time of his child's circumcision should say it before the child reaches puberty. If he says it, the child will be protected from the heat of iron, whether from killing or anything else."
