Volume 3, Book 27, Number 10:
Narrated Ata:
I heard Ibn ‘Abbas saying, “Allah’s Apostle asked an Ansari woman (Ibn ‘Abbas named her but ‘Ata’
forgot her name), ‘What prevented you from performing Hajj with us?’ She replied, ‘We have a
camel and the father of so-and-so and his son (i.e. her husband and her son) rode it and left one
camel for us to use for irrigation.’ He said (to her), ‘Perform ‘Umra when Ramadan comes, for ‘Umra
in Ramadan is equal to Hajj (in reward),’ or said something similar.”
