1. Islam: It is a condition because if a disbeliever performs Hajj, his Hajj will not be accepted by Allaah.
2. Maturity: It is a condition because it is not obligatory on the minors. And if the children perform Hajj it is correct and is considered as a Nafil (Voluntary) Hajj. After maturity He or She should perform the obligatory Hajj because the hajj performed before Maturity cannot fulfill the obligatory Hajj.
3. Mentally Sound: It is because the mentally ill person cannot have any will or intention.
4. Ability: A person should financially able to reach Kaaba. If someone lacks physical ability (Old aged or Sick or Physically Challenged etc) to perform Hajj, they should get their Hajj done by others.
Note: For women presence of Mahram comes under the condition of Ability. If she does not have a Mahram, then Hajj is not mandatory on her. If any women perform Hajj without Mahram, her Hajj will be correct, but she is sinful for such an action. She should sincerely repent.
