They were told that funeral procession was of one of the inhabitants of the land i.e. of a non-believer, under the protection of Muslims. They said, "A funeral procession passed in front of the Prophet (ﷺ) and he stood up. When he was told that it was the coffin of a Jew, he said, "Is it not a living being (soul)?
