Musannaf Ibn Abi Shaybah 34083 — Reports on Dhul-Qarnayn

Habib bin Himaz said: Sayyiduna Ali (may Allah be pleased with him) was asked: "How did Dhu al-Qarnayn reach the east and the west?" He said: "The clouds were made subject to him, light was spread out for him, and means were made ample for him." Then he said: "Shall I tell you more?" The man said: "No, that is enough."
