The Safina Society Curriculum Series seeks to inculcate the fundamental sciences of the Sharia within every-day working adults, students, and children, so as to raise the standard of the 'common Muslim.' Competence in tajwid is one of the most essential steps towards this goal. No Muslim should be shaky regarding the rules of Quranic recitation. Further, studying tajwid is from the fastest routes to bringing light into the heart, as it involves constant repetition of the Divine Speech.
