Is it permissible to play the Holy Quran in the car in the morning with the intention of listening and memorizing?

What you are doing by helping your children memorize the Holy Qur’an through repeated listening is a good deed, because memorizing, learning, and teaching the Qur’an are among the greatest acts of obedience; as the Prophet, peace and blessings be upon him, said: "The best among you are those who learn the Qur’an and teach it." The children should recite what they have learned to specialists to ensure the correctness of what they have acquired.
