(Al-An'aam) 6 : 143
ثَمَانِيَةَ أَزْوَاجٍ ۖ مِنَ الضَّأْنِ اثْنَيْنِ وَمِنَ الْمَعْزِ اثْنَيْنِ ۗ قُلْ آلذَّكَرَيْنِ حَرَّمَ أَمِ الْأُنْثَيَيْنِ أَمَّا اشْتَمَلَتْ عَلَيْهِ أَرْحَامُ الْأُنْثَيَيْنِ ۖ نَبِّئُونِي بِعِلْمٍ إِنْ كُنْتُمْ صَادِقِينَ
Eight pairs, two pairs of sheep, and two goats; you ask: "Does He forbid males in both or females in both, or what are the wombs carrying in both females? You inform me with the knowledge if you are so truthful".
