Abdul Hayy Lucknawi Firangi Mahali (24 October 1848 - 27 December 1886) was an Indian Islamic scholar of Hanafi school of Islamic thought.
Abdul Hayy was born in Banda, India. He was an Indo-Arab and a descendant of Abu Ayyub al-Ansari from Madinah through the lineage of the Sufi saint of Herat, Abdullah Ansari.[4]
After his father's death, he studied mathematics under his father's tutor, Muhammad Niamatullah. He taught for a while in Hyderabad. Subsequently, he left for Lucknow where he remained for the rest of his life.
He reportedly saw numerous companions of Muhammad in his dreams, including Abu Bakr, Umar, ibn Abbas, Fatimah, Aishah, and Umm Habiba. In his dreams he also claimed to have met Malik ibn Anas, al-Sakhawi, Jalaluddin Suyuti and other scholars, from whom he benefited as mentioned in one of his books.
The Grand Mufti of Makkah Ahmad Zayni Dahlan granted him permission for all isnad (chains of narration) from Al Hidayah of Burhan al-Din al-Marghinani, Muhammad Ibn Abdullah Hanbali of Makkah and Muhammad Ibn Muhammad Al-Gharbi. Abdul Ghani Dehlwi also granted him permission for various isnad.
He died in Rabi ul Awwal at the age of 38 and was buried in the graveyard of his ancestors.
