It is permissible to accept payment for teaching Qur’aan
Question

Is it right to take/accept money for teaching Quran?
Praise be to Allah.The Standing Committee was asked about whether it is permissible to accept payment for teaching Qur’aan. They replied: 
Yes, it is permissible to accept payment for teaching Qur’aan according to the more correct of the two scholarly views, because of the general meaning of the hadeeth:
“The thing for which you most deserve to take payment is the Book of Allaah,” (narrated by al-Bukhaari), and because there is a real need for that. And Allaah is the Source of strength. May Allah bless our Prophet Muhammad.
