Musannaf Ibn Abi Shaybah

Hazrat Hassan bin Abu Yahya narrates that a person asked Hazrat Saeed bin Jubair, "To whom should zakat be given?" He replied, "To the rulers (the leaders and kings)." The questioner said, "But Hajjaj bin Yusuf (who is the ruler) will use this money to build palaces for himself and will use it for purposes other than its rightful place (according to his desires)?" He replied, "You should act as you have been commanded (the burden of sin is on him)."
