Tafsir of Surah Al-Ahqaf 46:8
﴿أَمْ يَقُولُونَ افْتَرَاهُ قُلْ إِنِ افْتَرَيْتُهُ فَلَا تَمْلِكُونَ لِي مِنَ اللَّهِ شَيْئًا هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ كَفَىٰ بِهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ وَهُوَ الْغَفُورُ الرَّحِيمُ﴾
Translation of the meaning
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 Allāh 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."

فذكر سبحانه أنه شهيد بينه وبينهم ولم يقل: شاهد علينا ولا شاهد لي؛ لأنه ضمن الشهادة الحكم فهو شهيد يحكم بشهادته بيني وبينكم والحكم قدر زائد على مجرد الشهادة؛«مجموع الفتاوى» 14/194
