Abu Umama reported God’s messenger as saying, “He who is not prevented from performing the pilgrimage by an obvious necessity, a tyrannical ruler, or a disease which confines him at home and dies without having performed the pilgrimage, may die if he wishes as a Jew, or if he wishes as a Christian.”
‘A’isha said that she asked God’s messenger whether jihad was incumbent on women, and he replied, “Yes, jihad which does not include fighting is incumbent on them. It is the hajj and the ‘umra.”
Abu Huraira reported the Prophet as saying, “Those who perform the hajj and those who perform the 'umra are people who have come to visit God. If they supplicate Him He will respond to them, and if they ask Him for forgiveness He will forgive them.”
Ibn ‘Abbas said that the people of the Yemen used to perform the pilgrimage without bringing provisions, declaring that they put their trust in God; and when they came to Mecca they begged from the people. So God most high sent down, “And bring provisions, but the best provision is piety.’’(Qur’an 2:197)
