Ali İmran ﴾3-4﴿3. It is He Who has sent down the Book (the Qur'an) to you (O Muhammad صلى الله عليه وسلم) with truth, confirming what came before it. And He sent down the Taurat (Torah) and the Injeel (Gospel),4. Aforetime, as a guidance to mankind. And He sent down the criterion [of judgement between right and wrong (this Qur'an)]. Truly, those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, for them there is a severe torment; and Allah is All-Mighty, All-Able of Retribution.

Allah said: "Do you agree (to it) and will you take up My Covenant (which I conclude with you)?" They said: "We agree." He said: "Then bear witness; and I am with you among the witnesses (for this)."

Maide﴾44. Lo! We did reveal the Torah, wherein is guidance and a light, by which the prophets who surrendered (unto Allah) judged the Jews, and the rabbis and the priests (judged) by such of Allah's Scripture as they were bidden to observe, and thereunto were they witnesses.

Maide﴾45.

Unto Allah ye will all return, and He will then inform you of that wherein ye differ.
