Ubaid bin Umair said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them): What is the reason that you only perform Istilam (touching or kissing) of the two corners, the Yemeni Corner and the one with the Black Stone? He replied: If I am doing so, it is because I heard the Messenger of Allah (peace and blessings be upon him) say that by performing Istilam of these two corners, sins are forgiven. Also, Sayyiduna Ibn Umar (may Allah be pleased with them) said that the Messenger of Allah (peace and blessings be upon him) said: Whoever performs seven circuits (Tawaf) and then offers two units of prayer, he receives the reward equal to freeing a slave. Furthermore, he said that the Messenger of Allah (peace and blessings be upon him) also said that in Tawaf, for every step a person takes and places, ten good deeds are written for him, ten sins are forgiven, and ten ranks are elevated.
