وموضوعه: كلام الله تعالى من حيث دلالته على مراد الله تعالى
Its subject is the speech of Allah insofar as it indicates His intended meaning.
وغرضه: الاهتداء بهداية الله تعالى، والتمسك بالعروة الوثقى، والوصول إلى السعادة الأبدية
Its aim is to obtain divine guidance, hold fast to the firmest bond and attain enduring felicity.
Tafsir is therefore more than collecting vocabulary notes. It provides a disciplined basis for understanding belief, rulings, morals and conduct. Careful interpretation and acting upon guidance are related, but practice must be grounded in a faithful understanding of the revealed text.
