I say, and with God's success: The zakat (almsgiving) of the young is obligatory if there are older ones with it, and if they are all young, their zakat is not obligatory according to Abu Hanifa and Muhammad. However, it is obligatory according to Abu Yusuf, and one of them should be paid; as narrated by Abu Huraira (may Allah be pleased with him) who said: "When the Messenger of Allah (peace be upon him) passed away and Abu Bakr (may Allah be pleased with him) was fighting those who had disbelieved among the Arabs, Umar (may Allah be pleased with him) said: How can you fight the people? The Messenger of Allah (peace be upon him) said: I have been commanded to fight the people until they say there is no god but Allah. Whoever says it has protected his wealth and himself from me, except for his rights, and his account is with Allah. He said: By Allah, I will fight those who differentiate between prayer and zakat, for zakat is the right of wealth. By Allah, if they were to withhold a young goat that they used to give to the Messenger of Allah (peace be upon him), I would fight them for withholding it. Umar (may Allah be pleased with him) said: By Allah, it was only that Allah, the Glorious and Exalted, opened the heart of Abu Bakr (may Allah be pleased with him) and I knew that it was the truth." This is in Sahih al-Bukhari 2: 507. The young goat is the female offspring of a goat that has not yet reached a year. And from Sufyan ibn Abdullah (may Allah be pleased with him): "That Umar ibn al-Khattab (may Allah be pleased with him) sent him as a tax collector, and he was counting the people by the young goats. They said: Do you count us by the young goats and take nothing from them? When he returned to Umar ibn al-Khattab (may Allah be pleased with him), he mentioned that to him. Umar (may Allah be pleased with him) said: Yes, you count them by the young goat that the shepherd carries and do not take it." This is in Al-Muwatta 1: 265. And Allah knows best.
