Does bringing a reciter to recite the Quran and give out charity on behalf of a deceased child harm them or increase their good deeds, and is human death—even if it is a child's—an unchangeable, predetermined fate?

May Allah console your uncle for the loss of his daughter, and we ask Allah to unite her with him in the highest paradise. He should be reminded of the virtue of patience, and that his daughter was a trust from Allah, and He has taken back His trust. "Indeed, to Allah belongs what He has taken, and to Him belongs what He has given, and everything with Him has an appointed term. So let her be patient and anticipate Allah's reward." There is no doubt that every person has an appointed term, which they can neither delay nor advance. Reciting the Qur'an at condolence gatherings is an innovation. As for giving charity on behalf of the deceased, it is beneficial. Similarly, dedicating the reward of reciting the Qur'an to the deceased benefits them, according to the preponderant opinion. There is no difference in this regard between a child and an adult.
