Zakat in the Quran

The definition of zakaat becomes evident after proper studying of the word.
[Maryam 19:19] He said, "I am the messenger of your Lord, to grant you a (GHULAMAN ZAKIYYA) pure son."
[al-Kahf 18:74] So they went. When they met a (NAFSUN ZAKIYYA- pure, well built) young boy, he killed him. He said, "Why did you kill such an innocent person, who did not kill another person? You have committed something horrendous."
