Al-Adab al-Mufrad 853

Anas said, "While the Prophet, may Allah bless him and grant him peace, was in one of our palm groves where the trees belonged to Abu Talha, he went out to answer a call of nature. Bilal was walking behind him. The Prophet, may Allah bless him and grant him peace, honoured him by asking him to walk at his side. The Prophet, may Allah bless him and grant him peace, passed by a grave and stood there until Bilal reached him. he said, 'Woe to you, Bilal. Did you hear what I heard?' He replied, 'I did not hear anything.' He said, 'The man in the grave is being punished.' He found that it was a Jew."
