When a person donates reward to another, does the donator receive any reward?
After a in-depth study of prophetic narrations, we learn that the one donating reward is also not deprived of reward. Reward is recorded in the book of deeds of the donator and no reward will be decreased, rather more reward will be earned through īṣāl e-thawāb (donating reward); the reward of the good action itself and reward for donating to a fellow Muslim. If multiple individuals are donated reward, the reward will increase accordingly.
