If one is sincere, he would understand the Qur'an anyway, such a person would understand the command of the Qur'an as well. A sincere person loves Allah very much, he loves the Qur'an very much, he loves the companions and he loves everyone. Such a person would be perfect with his humility and morality. The whole matter is about sincerity because Allah makes such a person feel the things that are wrong, and see the right things as well. - Harun Yahya
