What is the ruling on intending to dedicate the reward of my studies to my mother's soul, given my desire to learn and teach despite the slow pace of my Quranic revision?

It is permissible to dedicate the reward of reciting the Qur’an to the deceased, and it will reach them. We congratulate you on teaching the sisters, and we advise you to persevere in it, for: "The best among you is he who learns the Qur’an and teaches it," and "No group of people gathers in one of the houses of Allah, reciting the Book of Allah and studying it among themselves, except that tranquility descends upon them, mercy encompasses them, and Allah mentions them among those with Him." There is no contradiction between the intention of learning and teaching the Qur’an and dedicating the reward to your mother.
