Question

A man and his old mother about 89 years old were selected to perform the Hajj in the year 2024. The mother felt very sick and is no longer able to travel for Hajj due to her severe sickness. Consequently, she could not go but her son went without her. Having already performed his own Hajj, Alhamdulillah! now her son wants to perform a Hajj Badal for her mother who is still alive. His mother has already made her provision to do Hajj. The ICC -Islamic Cultural Centre - responsible to organize Hajj in Mauritius, is refusing to let him do the Hajj Badal for her, despite her mother having still the right to do her Hajj without the need to do a fresh attempt to be selected. According to the ICC Conditions, her personal selection is still valid. She can do her Hajj at any moment. But the ICC refuses to let her son do the Hajj in her place. Has the ICC the right to do so? If yes, what can she do to be among those who have obeyed Allah's Commandment to accomplish the, Hajj the FIFTH PILLAR OF ISLAM?
