وَقَالُوا۟ مَا فِى بُطُونِ هَٰذِهِ ٱلْأَنْعَٰمِ خَالِصَةٌۭ لِّذُكُورِنَا وَمُحَرَّمٌ عَلَىٰٓ أَزْوَٰجِنَا ۖ وَإِن يَكُن مَّيْتَةًۭ فَهُمْ فِيهِ شُرَكَآءُ ۚ سَيَجْزِيهِمْ وَصْفَهُمْ ۚ إِنَّهُۥ حَكِيمٌ عَلِيمٌۭ
And they say: That which is in the bellies of such cattle is reserved for our males and is forbidden to our wives; but if it be born dead, then they (all) may be partakers thereof. He will reward them for their attribution (of such ordinances unto Him). Lo, He is Wise, Aware.
