6:144
وَمِنَ ٱلْإِبِلِ ٱثْنَيْنِ وَمِنَ ٱلْبَقَرِ ٱثْنَيْنِ ۗ قُلْ ءَآلذَّكَرَيْنِ حَرَّمَ أَمِ ٱلْأُنثَيَيْنِ أَمَّا ٱشْتَمَلَتْ عَلَيْهِ أَرْحَامُ ٱلْأُنثَيَيْنِ ۖ أَمْ كُنتُمْ شُهَدَآءَ إِذْ وَصَّىٰكُمُ ٱللَّهُ بِهَٰذَا ۚ فَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًۭا لِّيُضِلَّ ٱلنَّاسَ بِغَيْرِ عِلْمٍ ۗ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
And of the camels, two and of the cattle, two. Say, "Is it the two males He has forbidden or the two females or that which the wombs of the two females contain? Or were you witnesses when Allah charged you with this? Then who is more unjust than one who invents a lie about Allah to mislead the people by [something] other than knowledge? Indeed, Allah does not guide the wrongdoing people."

Tafsir
Ibn Kathīr (abridged)
These Ayat demonstrate the ignorance of the Arabs before Islam.
They used to prohibit the usage of some of their cattle and designate them as Bahirah, Sa'ibah, Wasilah and Ham etc. These were some of the innovations they invented for cattle, fruits and produce. Allah stated that He has created gardens, trellised and untrellised, and cattle, as animals of burden and as Farsh. Allah next mentioned various kinds of cattle, male and female, such as sheep and goats. He also created male and female camels and the same with cows. Allah did not prohibit any of these cattle or their offspring. Rather, they all were created for the sons of Adam as a source for food, transportation, work, milk, and other benefits, which are many. Allah said,
وَأَنزَلَ لَكُمْ مِّنَ الاٌّنْعَـمِ ثَمَـنِيَةَ أَزْوَجٍ
(And He has sent down for you of cattle eight pairs...) 39:6 Allah said;
أَمَّا اشْتَمَلَتْ عَلَيْهِ أَرْحَامُ الأُنثَيَيْنِ
(...or (the young) which the wombs of the two females enclose...) This refutes the idolators' statement,
