Does the reward of a deed decrease if one works or shares the reward of a righteous deed done for Allah (Mighty and Majestic) with another?

Question:
If you perform or share with someone the reward of a righteous deed you performed for Allah (Mighty and Majestic) and were sincere in it, does this mean that the reward of the deed for me decreases?

Answer:
Answer: Work is of two types: work in which acting on behalf of another is possible, such as charity, supplication, Hajj, and 'Umrah; the reward for this is transferred to others, whether living or dead, because there is evidence for this. As for work in which acting on behalf of another is not possible, its reward is not transferred to others, such as prayer, fasting, and other deeds. Since acting on behalf of another is not possible in these, their reward is not transferred to others because they are specific to their doer, as He (Exalted and Majestic is He) said: "And that man will have nothing but what he has earned."
