What is the ruling on giving Zakat to a student of knowledge?

It is permissible to give zakat to a student of Islamic knowledge who is dedicated to it, even if he is able to earn a living, because seeking Islamic knowledge is considered a form of jihad in the way of Allah, which is one of the categories for zakat mentioned in the Quran. As for a student of worldly knowledge, he is not given zakat, because he works for this world and can earn a living through employment.
