Ataa reported: I heard Ibn Abbas (RA) narrating to us that Allah's Messenger ( صلی اللہ علیہ وسلم ) said to a woman of the Ansar (Ibn Abbas (RA) had mentioned her name but I have forgotten it): 'What has prevented you that you do not perform Hajj along with us? She said: We have only two camels for carrying water. One of the camels has been taken by my husband and my son for performing Hajj and one has been left for us for carrying water, whereupon he (the Holy Prophet) said: So when the month of Ramadan comes, perform 'Umrah, for'Umrah in this (month) is equal to Hajj (in reward).
