Sayyiduna Abu Razin (may Allah be pleased with him) said: I said: O Messenger of Allah! Where was our Lord before He created the heavens and the earth? He (peace and blessings be upon him) said: "He was in a cloud ('ama'), with no air beneath it and no air above it; then He created His Throne upon the water."
