Muhammad bin Sirin said: A funeral passed by Sayyiduna Ibn Abbas and Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both). Sayyiduna al-Hasan stood up and Sayyiduna Ibn Abbas remained seated. Sayyiduna al-Hasan said: "Did the Prophet (peace and blessings be upon him) not stand for the funeral of a Jewish man or a Jewish woman that passed by him?" Sayyiduna Ibn Abbas said: "Yes indeed, and then he sat."
