Musannaf Ibn Abi Shaybah 33981 — Reports on what Allah gave Ibrahim

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When Ibrahim (peace be upon him) finished building the House of Allah, he was told: "Proclaim the Hajj among the people." He said: "O my Lord, how will my voice reach them?" Allah said: "You make the proclamation, and conveying it is My responsibility." So Sayyiduna Ibrahim (peace be upon him) said: "O people, the Hajj to the House of Allah has been made obligatory upon you." Everything between the heaven and the earth heard this call. Do you not see that people come to it from the farthest parts of the earth, calling out the Labbayk?
