Is the prayer of a seven-year-old girl accepted, and is the reward for her or for her parents?

The prayer of a discerning child who has reached the age of seven is valid, and the child is rewarded for their worship. This reward is specific to the child, according to the majority of scholars, based on the Prophet's (peace be upon him) saying: "Command your children to pray when they are seven years old." This is also evidence that good deeds are recorded for a young child, but bad deeds are not. As for her parents, they will be rewarded for being a cause of good if they command her to pray and encourage her to maintain it.
