AL AHQAAF (BUKIT-BUKIT PASIR) — Ayat 8
أَمْ يَقُولُونَ افْتَرَاهُ قُلْ إِنِ افْتَرَيْتُهُ فَلَا تَمْلِكُونَ لِي مِنَ اللَّهِ شَيْئًا هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ كَفَى بِهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ وَهُوَ الْغَفُورُ الرَّحِيمُ
Or do they say, "He has invented it?" Say, "If I have invented it, you will not possess for me [the power of protection] from Allah at all. He is most knowing of that in which you are involved. Sufficient is He as Witness between me and you, and He is the Forgiving the Merciful."
Tafsir
{Or} meaning “but” and the hamza of denial {they say, “He invented it”} meaning the Qur’an {Say, “If I invented it”} a duty {then you do not possess for me against Allah” meaning His punishment {anything} meaning you will not be able to repel it from me if Allah punishes me {He knows best what you conceal} they say about the Qur’an {Sufficient is He} the Most High {as a witness between me and you, and He is the Forgiving} of whoever repents {the Merciful} to him, so He did not hasten to punish you.
