It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: On the Day of Resurrection, it will be said to a person from among the people of Hell, "Tell me, if you had everything that is on the face of the earth, would you give it as ransom for yourself?" He will say, "Yes!" Allah will say, "I had asked you for something easier than this in the world. I had taken a covenant from you on the back of Adam that you would not associate anyone with Me, but you did not accept without committing shirk (associating partners with Allah)."
