Wasti is a surname originating from the city of Wasit, Iraq, from where the family emigrated to India.People with the last name Wasti or Zaidi are purportedly the direct descendants of the Prophet Muhammads great-grandson Imam Zain-ul-Abideen, whose real name was Ali ibn Husain (Ali son of Husain). Zaidi (or people belonging to this family) can be found all over the world, especially in Iran and Indo-Pak subcontinent.Some Zaidis are known as Wasitis. Zayd ibn Ali was martyred in Kufa, Iraq; many of his descendants either returned to al-Hijaz or remained in Iraq. Some of those who stayed in Iraq settled in Wasit. Some descendants from Wasit then moved to the Indian subcontinent. These Zaidis believe in twelve Imams and are part of Twelver Shiism. Most of them settled in India and Pakistan.
