Jundub reported God’s messenger as saying, “ If anyone interprets
the Qur’an in the light of his own opinion and is right, he has erred.”
Tirmidhi transmitted it.
Narrated ‘Amr b. Shu'aib quoted the authority of his father from his grandfather who said that the Prophet heard some people disagreeing about
the Qur’an and said, “It was just on this account that your predecessors
perished:
they set parts of God’s Book against others, whereas God's
Book was sent down only to be consistent; so do not use parts to falsify
others. Speak about as much of it as you know, but where you are ignorant entrust it to him who knows.” Ahmad and Ibn Majah transmitted it.
Ibn ‘Abbas reported God’s messenger as saying, “Let him who
interprets the Qur’an in the light of his opinion come to his abode
in hell.” A version has, “Let him who interprets the Qur’an without
knowledge come to his abode in hell.” Tirmidhi transmitted it.
