وَالْبُخْتُ وَالْعِرَابُ سَوَاءٌ.
Translation: Bactrian and Arabian camels have the same ruling.
Bukhṭ refers to a type of camel distinguished from the Arabian type, while ‘irāb are Arabian camels. Breed or regional differences do not change the prescribed camel-zakat brackets.
Thus the assessment at 5, 25 or 40 camels does not vary by breed. Both types belong to the single livestock category of camels for these rules.
