The Ottoman Empire has been collapsed in 1920s due our collective blunders and conspiracies of Pagan West or Capitalist World. The whole Muslim World had been moved under the direct or indirect control of Western powers. Peril of socialism has come into being and devouring the Muslim World. There were only few waves of awakening among Muslims but it was not possible for any Muslim region/country to live or survive without the shelter of capitalism or socialism. After the so-called World War II, the world has been categorically divided into two blocs - Red & White.
At this critical moment, there was no politically strong and economically powerful voice among Muslims against this imperial and Kafir (non-believers) setup. However, according to their traditional approach, the Muslim Aowliya were doing their work. They were purifying the individuals and developing a thought among Muslims for centralized structure of Islamic World. The way was steady and gradual, however, penetrating and stable. One such group of Aowliya that was working (and also presently working) for the individual purification and unity of Ummah was SILSILA QADRIA of Al-Syed Al-Sheikh Muhyiuddin Abdul Qadir Gillani (Allah bless his soul).
The most effective and powerful among Qadri group of Aowliya was Al-Gillani Al-Azizi family of Iraq. They are Nuqabah (custodians) of Darbar Ghousia, Al-Syed Al-Sheikh Muhyiuddin Abdul Qadir Gillani (R.A.). One of the saints of this family, Al-Syed Abdur Rahman Al-Qadri, had also remained Prime Minister of Iraq. After the death of Al-Syed Abdur Rahman, his noble son, Al-Syed Mahmood Hisamudin succeeded him. He had six sons. The youngest one was Al-Syed Tahir Allauddin Al-Qadri Al-Gillani (R.A.). He was born on 18th Rabi Ul-Auwal 1352 A.H./ 1932 A.D. in Baghdad, capital of Iraq. He is the 17th descendant of the Al-Syed Al-Sheikh Muhyiuddin Abdul Qadir Gillani (Allah bless his soul) and 28th descendant of The Holy Prophet Muhammad (Sallal lahu Alaihe Wassalam).
Al-Syed Tahir Allauddin Al-Qadri Al-Gillani (R.A) was the Qutb e Dora'n (the greatest spiritual guider of the time), Ghous e Zama'n (the greatest spiritual helper of the time), and Spiritual Mujadid (reformer of spiritual set up of Aowlyia and spiritual training program).
