Sahih Muslim Book 7, Hadith Number 2792.

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 that the Apostle of Allah (may peace be upon him) came to ‘Aisha (Allah be pleased with her) and she was weeping. The rest of the Hadith is the same.
