Musannaf Ibn Abi Shaybah

Hazrat Kharijah bin Zaid narrates from his uncle Hazrat Yazid bin Thabit that he was sitting with the Noble Prophet (peace and blessings be upon him) when a funeral procession passed by. When the Noble Prophet (peace and blessings be upon him) saw it, he stood up, and his companions also stood up, and they remained standing until the funeral had passed. I do not think that he stood up due to any discomfort or tightness of space, and I think it was the funeral of a Jewish man or woman. We did not ask the Prophet (peace and blessings be upon him) the reason for this standing.
