Musannaf Ibn Abi Shaybah

Hazrat Ibn Abi Laila narrates that Hazrat Qais bin Sa'd and Hazrat Sahl bin Hunaif were at Qadisiyyah when a funeral procession passed by them, so both of them stood up. It was said to them, "This is one of the people of the land (he is not a Muslim)." They replied, "Once a funeral procession passed by the Noble Prophet (peace and blessings be upon him), and he stood up. It was said to him, 'This is a Jew.' The Prophet (peace and blessings be upon him) said: 'Is he not a human being?'"
