Is it permissible to perform 'Umrah on behalf of another person if they are alive?

Question:
And does he perform 'Umrah for his wife and his brothers, who are well, and his sisters, who are well?

Answer:
We said: One does not perform 'Umrah for the living except if they are unable to perform the obligatory pilgrimage. If they are unable to perform the obligatory pilgrimage, and it has not been the case that they previously performed 'Umrah, and they are unable due to a continuous incapacity such that they cannot come, then he may perform 'Umrah al-Islam on their behalf. Likewise, he may perform Hajj al-Islam on their behalf if they have not performed Hajj, because they have become unable to do so. However, if they are able and in good health, he should not perform 'Umrah or Hajj on their behalf; they should come and perform 'Umrah and Hajj themselves.
