14 The Importance of Hajj Hajj is the 5th pillar of Islam. It is a once-in-a-lifetime obligation upon male and female sane adults who are eligible (whose health and means permit it). In the words of the Qur’an “Pilgrimage to the House is a duty unto Allah for mankind, or him/her who can find a way to perform it.” The Qur’an 3: 97. In carrying out this obligation, Muslims fulfill Allah’s call to Abraham: “And proclaim the pilgrimage among humankind. They come to you on foot and on every animal made lean by traveling deep, distant ravines.” The Qur’an 22: 27-28.
