Ibrāhīm Niasse (1900–1975)—or French: Ibrahima Niasse, Wolof: Ibrayima Ñas, Arabic: شيخ الإسلام الحاج إبراهيم إبن الحاج عبد الله التجاني الكولخي Shaykh al-'Islām al-Ḥājj Ibrāhīm ibn al-Ḥājj ʿAbd Allāh at-Tijānī al-Kawlakhī —was a major leader of the Tijānī Sufi order of Islam in West Africa. His followers in the Senegambia region affectionately refer to him in Wolof as Baay, or "father."
Niasse was the first West African to have led the Azhar mosque in Egypt after which he was honoured 'Sheikhul Islalm'. He became very close with many freedom fighters in West Africa due to his contribution for Independence in African States. The Sheikh became friends with Ghana's first President, Dr. Kwame Nkrumah who became fond of him and always sought advice from the Sheikh. Others such as Gamel Abdul-Nasser of Egypt were all friends to him. The then King of the Kingdom of Saudi Arabia Faisal, also loved him so much and respected him. Sheikh served as the Vice President of the World Muslim League with the King being the President.
His branch of the Tijāniyya, Tareeqa al-Tijaniyya al-Ibrahimiyya has become the largest branch in the world. After his death, the community was led by his closest disciple, Shaykh Aliyy Cisse and Niass' eldest son, Alhaji Abdulahi Ibrahim Niass. The current Khalīfa in Medina Baye is his eldest surviving son, Sheikh Ahmad Tijani Niass who became the khalifa in 2010 after the death of his brother khalifa Ahmadu Niass, known as “Daam”, on Tuesday 18 May 2010. Shaykh Ibrahim's role as principal Imam of the Medina Baye mosque has been carried out by the Cisse family. While serving as Medina Baay's Imam, Shaykh Hassan Cisse, Shaykh Aliyy Cisse's son and Shaykh Ibrahim's maternal grandson, carried Shaykh Ibrahim's teachings to the United States, United Kingdom and many other western countries. Shaykh Hassan Cisse was generally regarded as the leader of Tareeqa al-Tijaniyya al-Ibrahimiyya worldwide until his sudden death in August, 2008. Since then, Shaykh Hassan's younger brother Shaykh Tijānī Cisse has been given the position of Medina Baye's Imam. However, The current Grand khalifa Worldwide and the spiritual leader of Tijjaniyya ibrahimiyya is his Eminence.
Since the death of Shaykh Hassan Cisse and the taking over of Shaykh Tijānī Cisse as Imam of the Grand Mosque of Medina Baye, his junior brother Sheikh Mahi Cisse has continued the da'awah of Shaykh Hassan Cisse to the United States of America, Singapore, Malaysia, West Africa and other parts of the world. The Atlanta maulid of Sheikh Hassan Cisse has still been preserved.
