Al-Muqaddimah al-Ajurrumiyyah fi Mabadi’ Ilm al-Arabiyyah is a 13th-century book of Arabic grammar (نحو عربي). Written in verse for easy memorization, it formed the foundation of a beginner's education in Classical Arabic learning in Arab societies of the time and was one of the first books to be memorized after the Qur'ān along with the Alfiya. It was written by the Moroccan Berber Abu 'Abd Allah Sidi Muhammad ibn Da'ud as-Sanhaji (aka "Ibn Ajarrum")
