17. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Once, a people from Khurasan, from Transoxiana came to abu ‘Abd Allah عليه السلام. He (the Imam) asked them, ‘Do you shake hands with the people of your country and marry them? If you shake hands with them a ring of the rings of Islam is cut and if you marry them the privacy between you and Allah is violated.’”
