In his childhood he studied at Ambad shareef Dist. Jalna (M.R.) under the supervision of his father, Hazrath Syed Shah Ameen Biabani (R. A.). His father blessed him with khilafat. Later he studied at Aurangabad. After the death of his father, he migrated to Hyderabad with his brother, Hazrath Syed Shah Afzal Biabani –I (R.A.) alias shah saheb of Rajamundry. There he prosecuted his studies in ‘Islamic Sharia’ and became a great Islamic scholar. Due to the migration of Hazrath fazil Biabani-II (R.A.) from Ambad shareef, the mantle of sajjadgi (successorship) had fallen upon Hazrath Syed Ashraf sani (R.A.). Who was a great grand son of Hazrath Syed Aazam Biabani (R.A.), The second son of Hazrath Syed Shah Ziauddin Biabani (R.A.) Even today the sajjadgi is being continued in the family of Hazrath Syed Aazam Biabani (R.A.) Hazrath Ashraf Biabani’s chain is being continued at Kazipet, Warangal. The present (March’2001) Sajjada nasheen of Dargah shareef Kazipet is Hazrath Syed Shah Gulam Sarwar Biabani saheb, the great grand son of Hazrath Syed Shah Afzal Biabani (R.A.). Hazrath Syed Shah Fazil Biabani-II (R.A.) worked for a long time as a Taaluqa security officer under Meer Khaleel Khan, a land lord and ruler of Rajamundry and Elur during the reign of Nizam-ul-mulk Asif Jah. When Hazrath Afzal Biabani –I (R.A.) went for retreat (chilla kashi), Mirza Hasan Ali, a Journalist, became the administrator of Rajamundry. As he was a journalist, he was very close to Meer Khaleel Khan. He proposed the name of Mohammad Ali, son of Qazi of Rajamundry for the post of Taaluqa security officer.

Meer Khaleel Khan in principle accepted the proposal, Hasan Ali prepared the draft of appointment orders and it was ready to be presented before Khaleel Khan for his approval. Meanwhile the wind blew over the file awaiting approval and it carried away the draft proposal paper, which fell in nearby Godavari waters, leaving all the papers intact. This miraculous occurrence filled the people with great astonishment. Meer Khaleel Khan was a pious man. He said to Hasan Ali, ‘Allah do not want a change and Fazil Biabani saheb is a lucky man ‘. Meer Khaleel Khan felt very happy. He ordered his servant to bring the pandan and offered Hazrath Fazil Biabani (R.A), a betal leaf (pan ka beeda) as a mark respect. Hazrath Fazil Biabani’s faith in Allah enormously increased. He resigned the job. He visited a number of villages and preached Islam with great religious spirit. Thousands of people were attracted towards Islam. They embraced Islam and became his disciples.

Hazrath Syed Shah Fazil Biabani-II (R.A.) used to meditate, invoke and worship Allah near the bank of river ‘Godavari’. He offered Dogana Namaz-e-Mahboob Subhani continuously at mid nights for 24 years and got the blessings of Hazrath Shaik Abdul Qadir al Jilani Razi Allahu anhu.

He narrated an incident, he himself experienced at the monastery, in Rajamundry. After having completed the dogana namaz, he sat at the monastery facing towards west (Qibla). Within a short time drowsiness had overtaken him. But he was mentally fully awaken. He experienced a peculiar state, which was neither of sleepiness nor of wakefulness. It was in between. He dreamt that he was being pulled along by two persons. He asked them why were they doing so. They replied that they were going to present him before the king of kings. Who ordered them to do so. He was taken to a great court of saints. He was greatly astonished to see a number of saints from Arab and Aajam (non-Arabic countries) in the court.

He inquired one of the saints, the purpose for which he was brought there. He replied that Allah only knows better. The king was informed about his arrival. They were waiting for further orders. He was very much worried and sad expecting severe punishment orders. All of a sudden two persons came out of the court of the king. He inquired about the name of the king. They replied:” Hazrath Sultan-ul-Auliya Mohiuddin Syedna Shaik Abdul Qadir al Jilani Razi Allahu Tall Anhu”. When the two persons came near to him, he wished them. They kept their hands on his chest and said that his vow had been accepted, why it had not been completed so far. He said that he would definitely keep vow (mannath) with all reverence and sincerity then itself. He expressed his desire to meet and kiss the feet of the king. The soldiers conveyed his request to the king. The head saint said that he liked Fazil Biabani and asked to offer dogana namaz regularly. At that time Hazrath Shahabuddin Suherwardi (R.A.) and Hazrath Khaja Moinuddin Chishti (R.A.) were also present.

When Hazrath Fazil Biabani-II (R.A.) woke up he found himself facing towards the North (qutub). He prostrated sajda and then immediately arranged a votive feast (niyaz shareef). By virtue of his regularity in offering the dogana –e- Gousia he was blessed by the king of saints Hazrath Gous-e-Aazam Razi Allahu Taala anhu.

He was also blessed by Shah Mujaduddin (R.A.) (a khalifa of Hazrath Shaikain Ahmed Shattari (R.A.) 

Hazrath Fazil Biabani-II (R.A.) married to the grand daughter of Hazrath Syed Qutub –e-Aalam Bukhari (R.A.), Mufthi (The head of islamic scholars), Hyderabad and Mutawalli of a Masque called Qutub-e-Aalam Masque. Qutub-e-Aalam (R.A.) was very much impressed with his pedigree and ability. By the influence of the Mufthi of Hyderabad, Hazrath Fazil Biabani (R.A.) was appointed as Qazi of Warangal District and LandLord (Jagirdar) of three villages including Kazipet village. Thus he settled down with his family at Kazipet, which was later named after him as Kazipet (a village where Qazi resides).

In the year 1162 Hijri Hazrath Fazil Biabani (R.A.) once again visited Rajamundry. His brother Hazrath Syed Shah Afzal Biabani-I (R.A.) and his son, Syed Gulam Meer saheb, offered him warm welcome.

He received Khilafath from Hazrath Afzal Biabani-I (R.A.) also and learnt different methods of invocation and prayer. He returned to Kazipet.

He learnt different methods of invocations from Hazrath Syed Moinuddin Qadiri (R.A.) also. He wrote the book ‘ Punch Gunj’ in Persian language.

He died at Kazipet, Warangal. His holy grave is situated at Kazipet village opposite to the Afzal Manzil, few yards away from the Shariyat Manzil, the residence of the present Sajjada Nasheen.
