Abdul Qader Husni al-keilani al-Hasani (1874–1948) (Arabic: عبدالقادر حسني الكيلاني) was a Syrian nationalist, statesman and religious authority.

The family descends from a famous religious figure and greatest saint of his time, Sayyid Abdul Qader al-Jilani al-Hasani (1078–1166 AD), the father and founder of the Keilani Sufi order (also called Qaderiya) which still has thousands of followers all over the Islamic world today.

Soon after, the Keilanis became the leading family of the town, owing not only to the historical and religious significance of their ancestor but also to the fact that they belonged to the Ashraf class, the recognized descendants of the Islamic prophet Muhammad.

Members of the family also succeeded in gaining access to other important offices, such as that of the Mufti (the highest jurisconsult), the Qadi (the supreme Islamic Judge), and of course, they held on to their traditional leadership of the Sufi Qaderiyah sect, which prospered to a great extent during the Ottoman era.

Abdul Qader's father had died while he was a young child, and so he was raised by his maternal grandfather, Sayed Mohammad Ali al-Keilani, the Mufti of the city.

In February 1928, Keilani was chosen by Sheikh Taj al-Din al-Hasani to head the ministry of agriculture and trade in his newly formed government.

Some speculated that this was a ploy to distance Keilani from Hama where he had a growing base of popularity and influence and bring him closer to Damascus under the eyes of the French.

He briefly headed the Qaderiyah sect after the death of its leader Sayed Abdul-Jabbar Keilani, and was also elected to lead the committee that organized the well-known Hama Spring Celebrations.
