Here for your sake Lauki,
As per Mohyal folklore, a Mohyal of the Dutt clan had fought on behalf of Imam Hussain in the battle of Karbala, more specifically in the storming of Kufa- sacrificing his seven sons in the process. According to legend, Rahab Sidh Datt (also mentioned as Rahib Sidh or Sidh Viyog Datt in some versions) was the leader of a small band of career-soldiers living near Baghdad around the time of the battle of Karbala. The legend mentions the place where he stayed as Dair-al-Hindiya, meaning "The Indian Quarter", which matches an Al-Hindiya in existence today. The Dutts have traditionally been referred to as Hussaini Brahmins since times immemorial[4] Munshi Premchand's novel ‘Karbala’ also mentions about Hindus fighting for the sake of Imam Hussain, and refers to them as descendants of Ashwatthama, who the Dutt clan considers to be an ancestor. This legend occupies an important part in the Dutt clan's oral history,[5][6] and is considered a source of pride for them.[7
