It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that I asked the Holy Prophet (peace and blessings be upon him) about the meaning of this verse: "The sun runs to its resting place." The Holy Prophet (peace and blessings be upon him) said: The resting place of the sun is beneath the Throne.
