If I perform Umrah with the intention that its reward be for so-and-so, will the reward be for him alone or for both of us?

Whoever performs Umrah or Hajj on behalf of another is rewarded. Scholars have differed on the extent of the deputy's reward: whether he receives the reward for the acts of Hajj and Umrah, or if their reward is exclusive to the one on whose behalf they are performed, and the deputy only receives the reward for the acts of obedience he performs in the Haram.
