Umrah Badl is Umrah performed on behalf of one who is unable to perform Umrah. This may be due to physical fitness, an ongoing illness for which there is no hope of a cure, or because of old age and even for the deceased and the like. If one has the ability to recover from a sickness, then the person should wait until Allah heals him/her and then embark on Umrah independently.
Note - in order to have Umrah Badal done on behalf of a living person, permission must be given from the person.
