4. Ali ibn Ibrahim has narrated from his father from Hammad from Hariz from Zurarah who has said the following: “I once asked abu Ja‘far (a.s.), about performing Salah (prayer) behind a slave. He (the Imam) said, ‘It is not an offense if he has good understanding of fiqh (Islamic laws) and there is no one excelling him in fiqh (Islamic laws). He (the narrator) has said that he then asked, ‘Can I perform Salah (prayer) behind a blind man?’ He (the Imam) said, ‘Yes, if there is someone who shows him the direction and he is more excellent than others present.’ He (the Imam) then said, ‘’Amir al-Mu’minin (a.s.), has said, “No one of you must perform Salah (prayer) behind one suffering from leprosy, an insane man, one punished by law, one born of wedlock, behind a desert dwelling Arab and the immigrant (drifting) must not lead Salah (prayer)””’
