The zakah collector taking an animal older or younger than the required age

Ibrahim said: If the zakah collector takes an animal older than the prescribed one, he will give back two sheep or twenty dirhams; and if he takes an animal younger than the prescribed one, the zakah payers will pay two more sheep or twenty dirhams.

Amr bin Shu'ayb said: If the animal of the lower age is not found, he should take the animal of the higher age and give back to the owner of the livestock two sheep or twenty dirhams.

Abdullah bin Abd al-Rahman al-Ansari said: Umar bin Abdul Aziz wrote to some of his governors that, from a man in whose camels they did not find the ages due from him in zakah, they should not take anything other than those ages; rather, they should take the equivalent of his camels or a fair value.

Hammad said, concerning a man on whose wealth zakah had become due but who did not have it (the required animal): The two of them will return the excess to each other. (That is, whoever takes more will return something in exchange for it.)

Sayyiduna Ali (may Allah be pleased with him) said: If the zakah collector takes an animal younger than the age due, two sheep or ten dirhams are to be returned (as the difference).
