"What is Umrah on Behalf (عمرة البدل)?"
If a person is too severely ill to undertake the pilgrimage but meets the financial criteria, he or she should nominate someone else to make the pilgrimage on his or her behalf. He covers all of his proxy's expenditures, and the umrah is ascribed to him. God also lavishly rewards the person who performs the responsibility on his behalf. However, The sole requirement is that the individual performing umrah on behalf (عمرة البدل) of someone else must have already completed his own required umrah.
The pilgrimage and the Umrah are tasks that must be performed a minimum once in a person's lifetime if they are physically capable of doing so. The requirement for the obligation is based on 'ability.' Scholars have clarified that the ability in question includes both financial and physical capabilities. A person must be financially capable of covering all of his or her expenses, including transportation, food, lodging, and other expenses during the voyage, as well as the expenses of his or her dependents at home while he is away. A person who cannot afford to cover these costs is not obligated to perform this task.
