Badal Haji refers to the act of performing the pilgrimage of Hajj on behalf of another person who is unable to do so themselves due to valid reasons such as illness, old age, disability, or financial constraints. In Islam, Hajj is one of the Five Pillars and is obligatory for those who are physically and financially able to undertake the journey to the holy city of Makkah during the prescribed time of the Hajj season.

The concept of Badal Haji is similar to Badal Umrah, where a person undertakes the pilgrimage on behalf of someone else as a form of assistance and kindness. It allows individuals who are unable to perform Hajj themselves to fulfill the religious obligation through the proxy of another person.

Performing Hajj on behalf of others through Badal Haji is considered a virtuous and meritorious act in Islam, as it allows individuals to fulfill the religious obligation of Hajj for those who are unable to do so themselves. It reflects the spirit of compassion, solidarity, and community support within the Muslim community.
