Tafseer of The Morning Star · At-Taariq · 86:13
Indeed, the Qur'an is a decisive statement,
Important: The Arabic source text is always authoritative. This translation is a study aid and has not been verified by scholars — do not use it as a basis for religious proof or for deriving rulings (ahkam). When in doubt, always consult the Arabic text and a qualified scholar.
And His statement: ( إِنَّهُ لَقَوْلٌ فَصْلٌ — "Verily, it is a decisive word"). The Exalted, whose praise is exalted, says: verily, this word and this report is a decisive word; He says: a word that, through its clarity, makes a separation between the truth and the falsehood.
And in accordance with what we have said about this, the scholars of interpretation (ahl al-taʾwīl) have spoken, despite their mutual difference in its wording. Some said: a word of truth. And others said: a word of judgment.
