Munkar and Nakir are the two angels who question every soul in the grave (the Barzakh) immediately after burial. They are described in Hadith as having a terrifying appearance-black, with blue eyes, and immense in size. They ask three fundamental questions: 'Who is your Lord?', 'What is your religion?', and 'Who is your Prophet?'. The righteous believer will answer correctly, and their grave will become a garden of Paradise. The disbeliever or hypocrite will fail to answer, and their grave will become a pit of Hell. This trial emphasizes that our worldly choices have immediate consequences the moment we depart from this physical life.
