It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When I was taken up (to the heavens), I passed by people who had nails of copper with which they were scratching their faces and chests. I asked: 'O Jibril, who are these people?' He replied: 'These are the ones who eat the flesh of people (that is, they backbite them) and attack their honour.'"
No one narrated it from Abd al-Rahman bin Jubayr bin Nufayr (may Allah have mercy on him) except Safwan (may Allah have mercy on him), and Abu al-Mughirah (may Allah have mercy on him) is alone in narrating it.
