وَقَالُوا مَا فِي بُطُونِ هَذِهِ الْأَنْعَامِ خَالِصَةٌ لِّذُكُورِنَا وَمُحَرَّمٌ عَلَى أَزْوَاجِنَا وَإِن يَكُن مَّيْتَةً فَهُمْ فِيهِ شُرَكَاءُ سَيَجْزِيهِمْ وَصْفَهُمْ إِنَّهُ حَكِيمٌ عَلِيمٌ
And they say, ‘That which is in the bellies of these cattle is exclusively for our males and forbidden to our wives. But if it be still-born, they will all share it.’ Soon He will requite them for their allegations. Indeed, He is all-wise, all-knowing.
Agha Ali Puya Commentary
Commentary on Quran 6:139
[Pooya/Ali Commentary 6:139] These are some more pagan superstitions about cattle. Aqa Mahdi Puya says: The superstitious rites and rituals of the pagans, mentioned in verses 137 to 140, were deliberately introduced by the priests to exploit the ignorant people in the name of God. The laws and ordinances decreed by Allah are based upon reason and wisdom. Those who attribute such stupid superstitions to Him will be severely punished.
