Bismillahir Rahmanir Raheem
Hazrat Khawaja Ghareeb Nawaz Radi Allahu anhu did bait with Hazrat Khawaja Usman Haraooni Radi Allahu anhu who was the Qutb of his time. Khawaja Ghareeb Nawaaz states in his book Anees ul Arwah that when he travelled to Baghdad Shareef, he felt the desire to meet Khawaja Usman Harooni Radi Allahu anhu and found that he is present in the mosque of Hazrat Junaid Radi Allahu anhu to say his prayers. He reached there and found a party of scholars and saints gathered around him.
Khawaja Ghareeb Nawaaz Radi Allahu anhu stood up after receiving blessings from the Shaykh. Hazrat Usman-e-Haroon Radi Allahu anhu instructed him to read namaaz. He complied. Thereafter was instructed to sit towards the Qibla and read Surah Baqarah and thereafter Kalima SubhanAllah 20 times. Thereafter, Hazrat Usman-e-Harooni Radi Allahu anhu stood up and looked towards the skies and said, come I shall present you before Allah.
Thereafter, instructed him to sit down and read Surah Ikhlaas 1000 times. After finishing so, was instructed to spend a day and night in the worship of Allah. Khawaja Ghareeb Nawaaz Radi Allahu anhu did so and the second day came back. Hazrat Usman Harooni Radi Allahu anhu instructed him to sit down and immediately afterwards told him to look towards the sky. Khawaja Ghareeb Nawaaz Radi Allahu anhu said, I can see all the 2000 dimensions upto Arsh-e-Azam.
Thereafter, was instructed to look down. Khawaja Ghareeb Nawaz Radi Allahu anhu put his eyes down and could see Tahtas Saraa. Thereafter, was instructed to read Surah Ikhlaas a 1000 times again. Thereafter was asked to look up and to tell what he can see? Khawaja Ghareeb Nawaaz Radi Allahu anhu looked up and said, Hijaab-e-Azeem. Hazrat Usman Harooni Radi Allahu anhu told Khawaja sahab Radi Allahu anhu to look towards his fingers and asked, what do you see now? Khawaja Ghareeb Nawaz Radi Allahu anhu replied, EVERYTHING.
