Chapter 26: `Umrah (Minor pilgrimage)
Narrated Ata: I heard Ibn 'Abbas saying, "Allah' s Messenger (ﷺ) 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."
