Sahih Muslim Book 7, Hadith Number 2796.

Chapter : Types of Ihram- It is permissible to enter into the state of Ihram singularly for the sake of Hajj or for tamattu’ bi’l-‘umra ila’l-Hajj or for both hajj and ‘umra together.

Jabir b. Abdullah is reported to have said: Neither Allah’s Apostle (may peace be upon him) nor his Companions (circumambulated the Ka’ba and) ran between al-Safa and al-Marwa but once (sufficing both for Hajj and ‘Umra). But in the Hadith transmitted by Muhammad b. Bakr there is an addition: “That is first circumambulation.”
