Question: what is wilayat in islam?
Answer: Walayah or Walayat is a pillar of Shia Islam specifically in Ismaili and Druze denoting: "love and devotion for God, the Prophets, the Imam and the dai.". One should have Walayat (guardianship of the faith) on the wali. If someone has been made Wali of yours than have full walayat (guardianship of faith) of him.
