ذَٰلِكَ بِأَنَّهُمۡ قَالُواْ لِلَّذِينَ كَرِهُواْ مَا نَزَّلَ ٱللَّهُ سَنُطِيعُكُمۡ فِي بَعۡضِ ٱلۡأَمۡرِۖ وَٱللَّهُ يَعۡلَمُ إِسۡرَارَهُمۡ ٢٦
That is because they said to those who disliked what Allāh sent down,1 "We will obey you in part of the matter." And Allāh knows what they conceal.
Translation: Saheeh International (English)
1 i.e., the Jews of Madīnah.
Each word's meaning and sound
Such deviation occurred to them because they secretly said to the idolaters who hate the revelation that He had sent down to His messenger: We will follow you in some matters such as impeding the fighting. Allah knows what they keep hidden and what they make public. Nothing is hidden from Him and He will make apparent whatever He wishes to His messenger.
