Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman Madzillah-ul Aqdas, at the age of about 37, was so much absorbed in his spiritual relation with Allah that except job he shunned all worldly activities and spent most of his time in prayers, recitition of Holy Quran and Zikr of Allah's sacred names.These prayers were increasing day by day and search for divine reality had made him more and more restless. One day a strange man met him on his way and said to him in a strange manner that "the period of Allah's bounties has started for you, keep your inner condition just like it is". Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman asked him who he was? He said "I am the one who show way to people. I have come to guide you".
Through excessive prayers Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman was elevated to such spiritual heights where he got esoterically connected with Shaikh Abdul Qadir Jillani Razi Allahu Ta'ala Anhu who guided him spiritually and gave him the knowledge and command over all the attributive names of Allah. Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman invoked every name of Allah lacs of time and then was blessed with invocation (Zikr) of Ism-e-Allah and Ilm-e-Dawat. When his spiritual education was completed Shaikh Abdul Qadir Jillani Razi Allahu Ta'ala Anhu ordered him to find a Murshid-e-Kamil.
In this age of fraud it was very difficult to find a true murshid, still Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman continued his search. One night he saw a man with a beautiful enlightened face in his dream who said to him "come to me my son. I am waiting for you, you have suffered a lot of hardships, it is enough now". When Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman woke up he was greatly surprised at his dream and was worried as well because he didn't know where to go. His search continued for another month but in vain. After one month he again had the same dream. Now his restlessness reached its peak as he was unable to find that beautiful luminous face anywhere. His search came to an end when one day a friend of him Naveed Shaukat Sarwari Qadri asked him to go with him to his murshid who lived in Jhung near the shrine of Sultan Bahoo Rehmat-ul-Allah Alayh. When they reached there, to his deepest and heartiest contentment and happiness , Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman found that face of his dream sitting in front of him. When he entered the room, he clearly heard his murshid saying " oh you've come my son", it was a sentence heard by no one else present in the room. This esteemed person was Sultan Mohammad Asghar Ali Rehmat-ul-Allah Alayh . Sultan ul Ashiqeen Sultan Mohammad Najib-ur-Rehman Madzillah-ul-Aqdus swore allegiance upon his hands on the same day after Mughrib prayer. It was 12 April 1998.
