CIER Books are educational materials used in Islamic schools (madrasas) to teach subjects like Quran, Hadith, Fiqh (Islamic jurisprudence), Arabic language, and Islamic history. These books often focus on building a strong foundation in Islamic studies, moral values, and religious practices. Modern madrasa books are increasingly incorporating child-friendly teaching methods, such as activity-based learning, storytelling, and interactive exercises to engage students. Some also include visual aids, rhymes, and puzzles to make learning more enjoyable.
