Abū al-ʻAbbās Ahmad ibn Muhammad at-Tijāniyy or Ahmed Tijani (Arabic: أحمد التجاني, 1735–1815), was an Algerian Sharif who founded the Tijaniyyah tariqa (Sufi order).

He learned Quran under the tutelage of Mohammed Ba'afiyya in Aïn Madhi and also studied Khalil ibn Ishaq al-Jundi's Islamic jusrispudence works that were written under Malikite rites.

In his quest to seek a Sufi way of life, he met Sheikh Ahmad Abdullah El Hindi, who rarely saw people except for his servant.

Al-Samman told Tijani he will become a dominant qutb (pole) or scholar within the Sufi orders in the region.

[8] Tijani left Mecca and returned to Cairo where he got al-Kurdi's blessing to preach the Khalwatiyya order.

Though Sulayman disliked other Sufi orders, he provided Tijani a house and appointed him as a member of his learned council.

Trusted aides such as Abu Hafs' Abdul-Rahman was sent to Oran and Algiers and Abdul-Salam al-Waghiri to Constantine, Algeria.

Further muqaddams were appointed among learned converts including Muhammad Fuwadir al-Abdallawi in the Jarid district of Tunisia and Muhammed al-Hafiz in Mauritania.
