Ruling on specifying a value less than what is obligatory to pay from livestock

Q: When the collector comes to take the zakah of livestock, he has a fixed amount (a fixed value) with him, and this amount is less than the value of the animal, such that if its owner were to sell it, its value would be more than the fixed amount. Is it sufficient to pay the fixed amount?

A: There is no harm if he pays the authorities what they have assessed for him regarding the bint al-makhad, the bint al-labun, and others; because the obligatory amount is the middle one, so there is no harm if the authority exercises ijtihad and estimates the value.
