وَقَالُوا۟ لِجُلُودِهِمْ لِمَ شَهِدتُّمْ عَلَيْنَا ۖ قَالُوٓا۟ أَنطَقَنَا ٱللَّهُ ٱلَّذِىٓ أَنطَقَ كُلَّ شَىْءٍۢ وَهُوَ خَلَقَكُمْ أَوَّلَ مَرَّةٍۢ وَإِلَيْهِ تُرْجَعُونَ
And they say unto their skins: Why testify ye against us? They say: Allah hath given us speech Who giveth speech to all things, and Who created you at the first, and unto Whom ye are returned.
