Before, as guidance for the people. And He revealed the Criterion [i.e., the Qur’ān]. Indeed, those who disbelieve in the verses of Allāh will have a severe punishment, and Allāh is Exalted in Might, the Owner of Retribution.
Surah Al `Imran was revealed in Al-Madinah, as evident by the fact that the first eighty-three Ayat in it relate to the delegation from Najran that arrived in Al-Madinah on the ninth year of Hijrah (632 CE). We will elaborate on this subject when we explain the Ayah about the Mubahalah 3:61 in this Surah, Allah willing. We should also state that we mentioned the virtues of Surah Al `Imran along with the virtues of Surat Al-Baqarah in the beginning of the Tafsir of Surat Al-Baqarah.
بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ
In the Name of Allah, the Most Gracious, the Most Merciful
We mentioned the Hadith in the Tafsir of Ayat Al-Kursi 2:255 that mentions that Allah's Greatest Name is contained in these two Ayat,
Verse 3 which follows carries the reported proof of the Oneness of Allah. Briefly stated, it means that the principle of توحید tauhid as de-scribed in the Holy Qur'an is not something peculiar to the Qur'an or the Prophet of Islam. On the contrary, Allah Almighty has sent Scrip-tures such as the Torah and the Injil, and His prophets, in earlier times. And this was they all professed and this was they all brought as the message. When the Qur'an came, it simply confirmed their truth. It did not present any new claim which could pose problems for people in its understanding or acceptance.
The last two verses further fortify the doctrine of توحید tauhid on the ground that the attributes of encompassing knowledge and unlimited power are strong proofs of His being the One who possesses the eternal, and all-encompassing knowledge and whose power controls every-thing, and that He is the only One who rightly deserves to be wor-shipped. Anyone having imperfect knowledge and limited power can-not be entrusted with this exalted station.
(1.) Whenever the Holy Qur'an speaks of the 'Torah and the Injil' it refers to the original books revealed to the prophets Moses and Jesus (علیہ السلام) . This should not, therefore, be confused. With the present Old and New testaments.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 4–5
The Creator and Sustainer of the universe is not a mechanical God. He is, in fact, a live and conscious Being. He has sent guidance for man throughout the ages, including the Torah and the Bible, which were revealed to the former prophets. But man has always put different constructions upon divine teachings. Thus, through his self-styled interpretations, he has divided one religion into many. Ultimately, in accordance with God’s plan, the final book in the form of the Quran was sent down to man. The Quran is not only a genuine book of guidance but also serves as the criterion or standard of right and wrong. It tells us which is the true religion and which is the religion devised by human beings through misinterpretation. Now those who, denying the book of the Almighty, refuse to abandon the religion devised by human beings, are deserving of His punishment. These are the people to whom God granted eyes, but who failed to see the light (sent by God in the form of this book). These are the people to whom their Creator granted minds, but who failed to understand the truth when it came to them in the form of arguments. Bowing to the truth required them to bow to the Prophet and to God, and they thought that by surrendering to the Supreme Being and His Prophet they would diminish in stature. To save their petty ‘greatness’, they refused to bow to the Truth.
