Sahih Bukhari, Chapter: Minor Pilgrimage (Umra)

Abdullah the slave of Asma bint Abu Bakr, told me that he used to hear Asma, whenever she passed by Al-Hajun, saying, "May Allah bless His Apostle Muhammad. Once we dismounted here with him, and at that time we were traveling with light luggage; we had a few riding animals and a little food ration. I, my sister, Aisha, Az-Zubair and such and such persons performed Umra, and when we had passed our hands over the Kaaba (i.e. performed Tawaf round the Kaaba and between As-Safa and Al-Marwa) we finished our lhram. Later on we assumed Ihram for Hajj the same evening."
