Musannaf Ibn Abi Shaybah 12280 — Those who said one stands

Ibn Abi Layla said: Sayyiduna Qays bin Sa'd and Sayyiduna Sahl bin Hunayf (may Allah be pleased with them both) were at al-Qadisiyyah when a funeral passed by them, and they both stood up. It was said to them: "This is one of the people of the land (not a Muslim)." They said: Once a funeral passed by the Prophet (peace and blessings be upon him) and he (peace and blessings be upon him) stood up. It was said to him: "This was a Jew." He (peace and blessings be upon him) said: "Is it not a soul (a human being)?"
