It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said: "The names of the two angels who come in the grave are Munkar and Nakir, and the names of Harut and Marut, when they were in the heaven, were Azra and Uzayra."
No one narrated this hadith from Abdullah bin Kaysan (may Allah have mercy on him) except Isa (may Allah have mercy on him), and Ya'qub (may Allah have mercy on him) is alone in narrating it.
