Sultan-ul-Auliya Hazrat Sakhi Sultan Mohammad Abdul Aziz Rehmat-ul-Allah Alayh was born on 12th March 1911 (12 Rabi-ul-Awal 1329 H) in Garh Maharaja District Jhung Pakistan. His genealogical tree traces back to Hazrat Sakhi Sultan Bahoo in the eighth generation. He was born circumcised and with cut naval .His father Sultan Fateh Mohammad Rehmat-ul-Allah Alayh was a noble and pious saint.
When Sultan Mohammad Abdul Aziz was born, he didn't open his eyes for about seven days. His worried father took him to the shrine of Hazrat Sakhi Sultan Bahoo Rehmat-ul-Allah Alayh. Syed Bahadur Ali Shah Rehmat-ul-Allah Alayh was present at the shrine. Sultan Fateh Mohammad requested him to bless his son. When Syed Bahadur Ali Shah took Sultan Abdul Aziz in his lap he at once opened his eyes, thus Sultan Abdul Aziz's first glance was for his murshid, who spiritually blessed this pure soul since birth.
When Sultan Abdul Aziz Rehmat-ul-Allah Alayh was 21 years of age he took oath of allegiance at the hands of Syed Bahadur Ali Shah Rehmat-ul-Allah Alayh. Sultan Abdul Aziz, afterwards, dedicated his life in the service and love for his murshid. He never rode a horse or any other vehicle while going to meet his murshid, in his honour. Once he travelled 100 kilometers on foot to reach his murshid which shows the great honour and respect he had for his murshid. His mystic poetry is also full of his great adorance for his murshid. Even after the death of Pir Syed Mohammad Bahadur Ali Shah Rehmat-ul-Allah Alayh it was routine of Sultan Abdul Aziz to stay at his murshid's shrine, sometimes for 21 days or for 9 , 5 or 3 days.
When the treasure of Faqr was entrusted to Sultan Abdul Aziz Rehmat-ul-Allah Alayh, he devoted the rest of his whole life in guiding the seekers of Allah on the path of Faqr. Among his attributes most highlighting were his punctuality, patience, soberity and most of all great devotion for Allah almighty.
It was destined from eternity that Sultan Abdul Aziz Rehmat-ul-Allah Alayh will pass on the heritage of Faqr to his son Sultan Mohammad Asgher Ali who is stationed at the highest status of SULTAN-UL-FAQR (sixth) from eternity, so he didn't have to search for a true and capable devotee to entrust the treasure of Faqr.
Sultan Abdul Aziz Rehmat-ul-Allah Alayh died on 12th April 1981 (7th Jamadi-us-Sani 1401 H).
