Narrated from Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) that a man came to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Which part of the earth is the worst? The Prophet (peace and blessings be upon him) replied: I do not know. When Jibreel (peace be upon him) came to the Prophet (peace and blessings be upon him), he asked him this question, but he said: I also do not know, but I will ask my Lord. So he left, then after some delay or period, when he returned, he said: O Muhammad! You had asked about the worst part of the earth and I had said that I do not know, then I asked my Lord, so He said that the worst part of the surface of the earth is the marketplaces.
