Fiqh-us-Sunnah Volume 5, Hajj and ‘Umrah, Fiqh 5.071A.

Ibn ‘Abbas reported that Allah’s Messenger (peace be upon him) said, “Every day Allah descends a hundred and twenty folds of His Mercy to His slaves who perform Hajj (to His House). Sixty-fold of these are specified for people performing tawaf, forty-fold for those who pray there, and twenty for those who look at the Ka’bah.”

5. Upon completing one’s tawaf, one must offer a two rak’ah prayer at the Station of Ibrahim, reciting the verse of the Qur’an 2.125 “And take the Station of Abraham as a place of prayer.” This will complete one tawaf around the Ka’bah.

This tawaf is called Tawafal Qudum (Arrival Circumambulation), if a pilgrim is performing a mufrid (single) Hajj. Otherwise it is called Tawaf al Tahayya (Circumambulation of Greeting), or Tawafad Dakhul (Circumambulation of Entry). It is neither an essential condition nor an obligation. For a pilgrim performing Hajj Tamattu’ (combining Hajj and ‘Umrah with a break), or performing Hajj Qiran (combining Hajj and ‘Umrah without a break), it is Tawafal ‘Umrah (‘Umrah Circumambulation), and after having performed it a pilgrim does not need to perform a Tawafal Tahaya or Tawafal Qudum. Such a pilgrim must, however, complete his ‘Umrah making a Sa’i (seven rounds of walking) between the hills of Safa and Marwah.
