The importance of teaching Arabic to our children at an early age cannot be over emphasized. Arabic is the language in which both the Qur'an and Sunnah are conveyed to the believers. Arabic also serves as a medium of communication between Muslims.
Allah, Subhanahu wa Ta'ala, through his infinite wisdom has given children the unique ability to learn second and third languages easier than adults have. Therefore, it is important for parents to take advantage of this "critical period" to teach and speak Arabic within the home to their children.
