Fiqh-us-Sunnah Volume 5, Hajj and ‘Umrah, Fiqh 5.090A.

Making supplications, remembrance of Allah, and reciting the Qur’an while walking between Safa and Marwah are all desirable. It is reported while making Sa’i the Prophet (peace be upon him) used to supplicate, “O my Lord, forgive me, have mercy upon me, and guide me to the straight path.” Also he used to supplicate, “O my Lord, forgive me, and have mercy upon me. You are the most Honorable, most Dignified.”

After performing Tawaf and Sa’i a pilgrim completes the rites of ‘Umrah. Similarly a person performing Hajj Tamattu’ may terminate his state of ihram by clipping some of his hair short or else shave it all. However, a pilgrim should keep his state of ihram if he is performing Hajj Qiran. Such a pilgrim may terminate his state of ihram on the Day of Sacrifice (Yaum un-Nahr) after the sacrifice. For a qarin pilgrim, this Sa’i will suffice in place of the one other pilgrims are required to make after Tawafal Fard when they return from Mina. As for those pilgrims who join Hajj with ‘Umrah with a break in between (i.e., who make Hajj Tamattu’), they must perform another Sa’i and stay in Makkah until Yaum al-Tarwiya (the 8th of Zhul-Hijjah).
