His teachers in Fez observed his scientific competences and perseverance in his work. They therefore allowed him to teach .[2][1] He was known for his purity, generosity, boldness and courage, and his determination as well as his eloquence and humility he was religious and proud of his Islamic personality and protective of his religion and language even when surrounded by Europeans.[2]

-Abdelkader Medjaoui
— "The Arabic language is one of the oldest languages in the world used today and one of the most extensive, I prefer it to other languages. Even a non-Arabic speaker uses it to make his declaration of faith. It is the most eloquent language in logic and demonstration, which best expresses dialectics, the most artistic in prose and poetry. Allah has filled it with arts and wisdom .He alone knew how to take advantage of old and new proverbs."
He died in Constantine, Algeria on October 6, 1914, leaving behind him a good trace: his students and scholars who followed his path as well as deeds represented in books and writings which varied in type and quality.[2][1]
