It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that he said: "The Messenger of Allah (peace and blessings be upon him) forbade shaking hands with the polytheists, calling them by their kunyah (as a mark of honour), or welcoming them (by saying 'Marhaba')."
Musnad Ishaq bin Rahwayh: 2839. The narrator in its chain, Muhammad bin Muslim al-Qushayri, is da'if (weak), because of which this report is weak in its chain.
