Al-Kāfi 6, narration 68

Translation

12. Al-Husayn ibn Muhammad has narrated from Mu‘alla’ ibn Muhammad from Muhammad ibn Muslim from al-Husayn ibn Nasr from his father from ‘Amr ibn Shamir from Jabir who has said the following: “Abu Ja‘far (a.s.), once wanted to visit one of his followers because he was ill. He (the Imam) told me to follow him and I followed him (the Imam). When he (the Imam) arrived at his door his small son came out and abu Ja‘far (a.s.), asked, ‘What is your name?’ He replied, ‘It is Muhammad.’ He (the Imam) asked, ‘What is your Kunyah ?’ He replied, ‘It is Ali.’ Abu Ja‘far (a.s.), then said, ‘You have fortified yourself against Satan very intensely. When Satan hears someone calling O Muhammad, O Ali, Satan melts like lead until he hears someone calling with the names of our enemies; he becomes excited and swaggers.’”
