The Ruling on the Good Deeds of Children and Hajj for a Minor

Question:
The questioner asks: Regarding the good deeds of young children, those who are seven or six years old, such as prayer and dhikr, do these count for them or for their parents?

Answer:
As for Hajj, it is valid for both the minor and the adult, for the one who has reached the age of discernment and for the one who has not, because a woman brought a child to the Prophet (peace and blessings be upon him) and said, "This is Hajj for him." He said, "Yes, and you will have a reward." For the one who has not reached the age of discernment, his guardian intends on his behalf; his guardian intends the ihram on his behalf.
As for the one who has reached the age of discernment, he intends it himself. This is regarding Hajj and 'Umrah. As for the other deeds, the one who has not reached the age of discernment, his deeds are not valid because he does not have intention, and there is no evidence for that. As for the one who has reached the age of discernment, his acts of worship are valid and count as voluntary for him, and his guardian gets a reward for his saying: Likewise, they are commanded to fast if they can bear it, as a means of training, and they get the reward of voluntary deeds, and their guardians get the reward of proper upbringing.
