It is narrated from Ubaid bin Umair that he said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them): "You push through people and enter the crowd to touch the Black Stone and the Yemeni Corner. (What is the reason for making such a strong effort?)" He replied, "If I do this, (the reason is that) I heard the Messenger of Allah (peace and blessings be upon him) say: 'Sins are forgiven by touching these two.' And I heard him say: 'For every step a person takes while performing Tawaf of the Sacred House, Allah writes a good deed for him, erases a sin, and raises him one degree.' And I heard him say: 'Whoever completes seven circuits, it is as if he has freed a slave in reward.' In the narration of Yusuf, it is mentioned: 'And one degree is raised for him.'"
And the mention of recording a good deed, raising a rank, and removing a sin from the one performing tawaf with every step he lifts or sets down during his circumambulation, and granting the one performing tawaf, for counting a week of tawaf, the reward of freeing a slave, as the Prophet, peace and blessings be upon him, made the one who completes a single week of tawaf like one who frees a slave.
