Qur'an 6:143

ثَمَـٰنِيَةَ أَزْوَٰجٍ ۖ مِّنَ ٱلضَّأْنِ ٱثْنَيْنِ وَمِنَ ٱلْمَعْزِ ٱثْنَيْنِ ۗ قُلْ ءَآلذَّكَرَيْنِ حَرَّمَ أَمِ ٱلْأُنثَيَيْنِ أَمَّا ٱشْتَمَلَتْ عَلَيْهِ أَرْحَامُ ٱلْأُنثَيَيْنِ ۖ نَبِّـُٔونِى بِعِلْمٍ إِن كُنتُمْ صَـٰدِقِينَ

Eight pairs: Of the sheep twain, and of the goats twain. Say: Hath He forbidden the two males or the two females, or that which the wombs of the two females contain? Expound to me (the case) with knowledge, if ye are truthful.
