Umrū bin Noman Juhfi says that there was a friend of Imam Ja’far as-Sadiq (a.s.). He always remained with the Imam (a.s.) wherever he went. He had a slave who was from Sind. One day, the person was passing through the market of shoe-makers with Imam (a.s.) while his slave walked behind. The master wanted to send the slave on an errand, but when he looked back the slave had disappeared. He looked back Three times but could not see the slave. After some time, when he looked for the fourth time, he saw the slave. He was angry with him and said, “O’ son of the adulteress! Where were you?”
The narrator says that Imam Ja’far as-Sadiq (a.s.) slapped his forehead and said,
“Glory be to Allah! You are accusing his mother of adultery. And I was seeing some piety in you, but now I find that there is no sign of piety or religiousness left.”
The companion protested,”May I be sacrificed upon you, his mother is an inhabitant of Sind (India) and she is a Mushrik (polytheist).” Imam (a.s.) replied,
“Don’t you know that all people have their own type of marriage? Be away from me!”
The narrator says, “In the Imam’s life-time, I never saw him walking with Imam (a.s.), again.”
Another tradition states,
“All the people have their kind of marriage due to which they protect themselves from adultery.”5
Abul Hasan al Hazzae says that he was in the company of Imam (a.s.) when a person came and asked him, “What did your debtors do?” I responded, “Are you asking about the son of that adulteress woman?” Upon hearing this Imam Ja’far as-Sadiq (a.s.) glared at me in anger. I said, “May I be sacrificed upon you. He is a Majūs (fire worshipper) and his mother is also his sister (means that his father had married his daughter). Imam (a.s.) asked,
“Is not this type of marriage permitted in their religion?”
