In The Name of Allah, The Most Merciful, The Bestower of Mercy

Allah [The Exalted] said:

وَكَذَٰلِكَ نُفَصِّلُ الْآيَاتِ وَلِتَسْتَبِينَ سَبِيلُ الْمُجْرِمِينَ

And thus do We explain the signs (to you O Muḥammad) in detail, and so that the way of the criminals may become evident (to you)] [Surah Al-An’aam. Aayah 55] (1)

Imam Ibn Katheer [may Allaah have mercy upon him] stated regarding this Ayah: “Allah [The Exalted] stated that just as He explained what was previously explained of the arguments and evidence on the path of guidance and sound judgement, and censured argumentation and stubbornness; likewise He explains the signs (proofs, evidences, lessons), which those being addressed are in need of; [ولتستبين سبيل المجرمين – and so that the way of the criminals may become evident (to you)]. Meaning, so that the path of the criminals – those who oppose the Messengers – may become evident”. (2)

Imam At-Tabari [may Allah have mercy upon him] stated regarding the statement of Allah: [وكذلك نفصل الآيات – And thus do We explain the signs (to you O Muḥammad) in detail]- Meaning, O Muhammad! Just as We have detailed for you in this Surah – from its beginning and introduction up to this point – our proofs and evidences against the idolaters and worshippers of images, and distinguished and clarified it for you; likewise, We explain to you our signs and evidences for every truth denied by the people of falsehood, the sects and other than them, until its truth is distinguished from its falsehood, and its right is distinguished from its wrong. (3)

Allah [The Exalted] said:
وَلَا يَأۡتُونَكَ بِمَثَلٍ إِلَّا جِئۡنَـٰكَ بِٱلۡحَقِّ وَأَحۡسَنَ تَفۡسِيرًا

And they bring no (argument or objection by way of a) similitude (to criticise this Qur’ān and oppose your message) except that We bring you the truth and the better explanation thereof (through a similitude that is superior to theirs, provides detail and invalidates their objection). (4)

[وَلَا يَأۡتُونَكَ بِمَثَلٍ – And they bring no (argument or objection by way of a) similitude]- Meaning, by which they (attempt) to oppose and repel the truth as well as your message; [إِلَّا جِئۡنَـٰكَ بِٱلۡحَقِّ وَأَحۡسَنَ تَفۡسِيرًا – except that We bring you the truth and the better explanation thereof (through a similitude that is superior to theirs, provides detail and invalidates their objection)]- Meaning, We sent down to you the Qur’an, which has all truth in its meaning, as well as clear and flawless elucidation of its wordings, because all of its meanings are truth and credibility, not tainted by falsehood or doubt from any angle. (5)
