17. Muhammad ibn al-Husayn has narrated from Ja‘far ibn Bashir from ibn Bukayr from Zurarah who has said the following: “I once heard abu Ja‘far , saying, ‘A man would come to Ali ibn al-Husayn , and his Kunyah was abu Murrah. When asking for permission at the door he would say, ‘

This is abu Murrah at the door.’ Ali ibn al-Husayn , said to him, ‘I swear you to Allah that when you come to our door do not say, ‘This is abu Murrah at the door (it is Kunyah of Satan).”’
