It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that Ubayd bin Umayr (may Allah have mercy on him) asked him: Why is it that I see you touching (istilam) only these two corners of the House of Allah, namely the Black Stone and the Yemeni Corner? Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Indeed, touching the two of them sheds sins.' And I heard him (peace and blessings be upon him) saying: 'Whoever completes seven circuits of the House of Allah and offers two rak'ahs will have a reward equal to freeing a slave.' And I also heard him (peace and blessings be upon him) saying: 'A man does not raise his foot nor place it on the ground (during tawaf) except that ten good deeds are recorded for him in return, ten of his sins are wiped out, and he is raised ten degrees.'"
