The literal meaning of tafsir in the Arabic language is to open or to explain, interpret or comment. Technically, the science of tafsir is a branch of knowledge in which the meanings of the Quran are explained and its injunctions and wisdoms are described openly and clearly (al-Burhan). Addressing the Holy Prophet, the Glorious Quran says:
We revealed the Quran to you so that you explain to the people what has been sent down to them. (16:44)
The Holy Quran also says:
Surely, Allah did a great favor to Muslims when He sent a Messenger to them from among them who would recite His verses before them and purify them and teach them the Book and the Wisdom. (3:164)
Keeping this in view, it should be noted that the Holy Prophet not only taught the words of the Quran to the people but he also explained them in detail. This is why, on some occasions, the revered Companions had to devote years at a time to learning a single surah.
Until such time that the Holy Prophet graced the mortal world with his presence, seeking the explanation of a Quranic verse did not pose much of a problem. When the Companions faced any difficulty in understanding a verse, they would simply turn to the Prophet (upon him blessings and peace). Later, however, it became necessary that the tafsir of the Quran be preserved as a permanent branch of knowledge so that, along with the words of the Noble Quran, its correct meaning remain protected and conserved for the Muslim Ummah as well, and so heretics and deviants could find no room for distortion of its meanings. So, with the grace and tawfiq of Allah Almighty, the Ummah accomplished this wonderful mission with such efficiency that today we can say without any doubt or fear of rebuttal that not only have the words of this Last Book of Allah been protected but also its correct explanation transmitted to us through the Holy Prophet and his Companions.
