Khwaja Usman Harooni was an early day Sufi Saint, a successor to Shareef Zandani, fourteenth link in the Sufi Silsilah of the Chishti order, and the Master of Moinuddin Chishti. Usman Harooni was born in Haroon, Iran. His year of birth is variously given as 1096, 1116 and 1131 AD (490, 510 and 526 AH). He is also known by his nicknames, Abu Noor and Abu Mansur.
When he was rather young, he came in touch with an absorbed mystic (majzub) called Chirk. This association with Chirk brought about a significant transformation in his life. As a result, the material world lost its charm for him and he decided to embrace a higher moral and spiritual life.
Usman Harooni went to meet Shareef Zandani, a renowned mystic and saint of the Chishti order, with a request to be enrolled as his spiritual disciple. Shareef Zandani found him to be a fit person and accepted the request, by placing a four-edged cap upon the head of Usman Harooni.
He then told him that the four-edged cap implied the following four things:
- First is the renunciation of this world;
- Second is the renunciation of the world hereafter;
- Third is the renunciation of the desires of the self;
- Fourth is the renunciation of everything other than God.
Usman Harooni spent over thirty years in the company of his spiritual guide. During this period, he was engaged in ascetic practices and prayers. As time passed, he gained many spiritual accomplishments. He was then asked by his spiritual guide to move on and spread the gospel of truth.

Message and teachings 
According to Usman Harooni, a great man is one who is endowed with virtues like contentment, sincerity, self-abnegation, self-sacrifice and above all, spirit of renunciation. He said that the ego in a man was an enemy, as it did not allow him to think rationally, act wisely and live happily. He emphasised that unless a man loves human beings, it is impossible for him to love God.
