1- Islam: Faith is the first requirement and without it the prescribed deeds are not valid or accepted as acts of worship. As we have seen previously, there is a strong relation between Hajj and its rituals with the religion of Ibraheem (A), which is the religion of Tawheed.
2- Sanity: Anyone who is not sane-minded - somebody who is proven to be is mentally ill - is not held responsible for his, or her, actions. The Prophet (S) said,
"There are three kinds of people who are not held responsible for their actions: The sleeping person until he wakes up, the child until he reaches the age of puberty, and the mentally ill until he becomes sane." [Related by the Five and ad-Daarimi]
3- Puberty: As understood from the above hadith.
4- Ability: It was explained by the Messenger of Allah (S) as the transportation and the provision during the journey. Today, Hajj is done through special arrangements and requirements. Anyone who can fulfill those requirements and can afford to pay for his journey without begging others or taking loans should go for Hajj.
"Pilgrimage thereto is a duty men owe to Allah, those who can afford the journey"
