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 , 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 , 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 , 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.’”
