Abdulqadir Gilani

Abdulqadir Gilani (Arabic: عبد القادر الجيلاني) was an Islamic scholar and ascetic who lived in Baghdad and is regarded as the spiritual founder of the Qadiriyya, one of the most widespread Sufi orders in the world. He came from the Jilan region (Gilan) south of the Caspian Sea, from which he took his name. He moved to Baghdad in his youth to study, where he became a teacher and preacher.

His teaching was grounded in Hanbali jurisprudence and hadith scholarship, but he became known for public sermons emphasizing repentance, piety, and moral reform. After his death, his name became central to numerous Sufi lineages across Africa, Asia, and Europe. His tomb in Baghdad remains a site of visitation and pilgrimage to this day.

Life and education

According to historians, Gilani was born in the Jilan region in the eleventh century and traveled to Baghdad to study at its madrasas. At that time Baghdad was a major center of learning under the Abbasid Caliphate. He studied jurisprudence, hadith, and Arabic before spending a period in solitary ascetic practice outside the city. Upon returning to public teaching, he was given leadership of a madrasa and a ribat (Sufi lodge) in Baghdad.

Teaching and writings

His teaching combined Islamic jurisprudence with spiritual discipline. Works attributed to his name include the "Al-Ghunya li-Talibi Tariq al-Haqq," a guide to worship and ethics, and collections of sermons called the "Al-Fath al-Rabbani" and "Futuh al-Ghayb." These texts were often compiled by his students and successors, meaning some material may derive from recorded sermons rather than compositions by Gilani himself.

The Qadiriyya order

The Qadiriyya is a Sufi order whose spiritual chain of transmission traces back to Gilani. There is no evidence that he himself established a formally organized movement; rather, his descendants, students, and followers in subsequent centuries built networks of teaching and pilgrimage centered on his name. The order spread throughout North Africa, the Horn of Africa, India, Turkey, and Kurdistan (Kuriyaha). It typically features practices of collective recollection (dhikr), recitation of litanies, and a relationship between master and disciple.

Impact on Somalia and the Horn of Africa

In the Horn of Africa, the Qadiriyya was one of the earliest Sufi orders to arrive and played a role in Quranic education, resolving community disputes, and establishing religious communities called jamaaca. Annual commemoration of Gilani, called in some places "siyaaro" or "the mawlid of Sheikh Abdulqadir," is part of the religious calendar in many regions. Several Somali scholars composed Arabic poems in his praise.

Veneration and dispute

Gilani's tomb in Baghdad has become a major pilgrimage site, with a mosque and school built nearby. The practice of visiting tombs and commemorating saints is contested among Islamic groups: some Salafi movements object to certain forms of such veneration, while Sufi orders view it as part of religious custom. This disagreement has affected Somalia and other countries since the twentieth century.
