One of the earliest settlements of Naqvi's is reported from Jais, Raibareli in North India. Naqvi Sadats migrated from SUBZWAR (IRAN) & arrived in Jais around 410 Hijri (around 1027 A.D.) and settled here. After some time adjacent Patakpur, 7 mile from Jais, was also inhabited by Momineens and rechristened as Naseerabad after the name of Syed Naseerudin Jaisi. Jais & Nasirabad are the earliest known Naqvi Sadats of India. Jais & Naseerabad are the native land of Khandan e Ijtihad and multitude of very high ranking scholars have come from there. The 1st Mujtahid from India, Ayatullah il Uzma Sayyid Dildar Ali Naqvi 'Gufraanmaab (ar)' was from here and later his family came to be called Khandan e Ijtihad due to the heavy presence of high ranking scholars. Some famous and known religious scholars from this lineage include Syedul Ulema Ayatullah Syed Ali Naqi Naqvi 'Naqqan', Jannat Ma'ab Ayatullah Syed Mohammad Naqvi, Ayatullah Aqa Hasan Sb, Ayatullah Syed Kalbe Hussain Naqvi, Hujjatul Islam Syed Kalbe Abid Naqvi, Hujjatul Islam Syed Kalbe Jawwad Naqvi, Hujjatul Islam Syed Hasan Zafar Naqvi(based in Karachi), Allama Nasir Ijtehadi, Dr Kalbe Sadiq, Hujjatul Islam Syed Ali Mohammad Naqvi.
