Musannaf Ibn Abi Shaybah 13065 — Reports on the reward of Hajj

Abu al-Duha says: An old man in this mosque informed me that Sayyiduna Umar (may Allah be pleased with him), delivering a sermon near the Ka'bah, said: "There is no one who comes to this House (the House of Allah), with nothing bringing him out from home except praying here, until he kisses the Black Stone, except that this deed becomes an expiation for all his previous sins."
