Syed Abdur-Razzaq Nurul-Ain is the successor of the Sufi saint Syed Ashraf Jahangir Semnani.  From amongst the descendants of Syed Abdul Razzaq Jilani, the line of saints of Ashrafia Jilania is one of the most reputed households belonging to the Indo-Pak subcontinent.  Within this line, Syed Abdul Razzaq, popularly known as Nur-ul-Ain, was the heir, disciple and Khalifa of Syed Ashraf Jehangir Semani.  Syed Abdul Razzaq was the son of his maternal cousin.  Syed Abdul Razzaq is the 11th descendant of the greatest Sufi Syed Abdul Qadir Jilani of Jilan, Iraq.  Abdur-Razzaq Nurul-Ain first met Ashraf Jahangir Semnani at the age of twelve years in Baghdad when Ashraf Jahangir Semnani made a visit there and from there on never parted from his company.  He adopted Syed Abdul Razzaq as his son and made him the heir and caretaker.  Originated from the name of Syed Ashraf, this line of saints is still called as Ashrafia.  Syed Ashraf Jehangir Semani died in 808 AH and Syed Abdul Razzaq became the heir to his throne.  After strenuous spiritual training he was bestowed with Khilafat (Spiritual Successor) and from him the Ashrafi spiritual chain flourished.

In Tohfta ul Abrar, his age is written as 120 and year of birth is 688 AH.  Even his adopted son, Syed Abdul Razzaq was 120 of age at the time of his death.  He spent 12 years before he took Bayat and 68 years in travel and in the service of Syed Ashraf Jehangir Semani and the remaining 40 years after the death of his Murshid at the throne of Khilafat.  In accordance to this, his birth year becomes 728, year of arrival in India 740 and year of death 848.  His grave is located next to that of Ashraf Jahangir Semnani in the same Shrine in Kichauccha Sharif, Dist.  Ambedkar Nagar, Uttar Pradesh, India.
