The uniqueness appearance of Nasrid motto “Lâ ghâlib ilâ Allâh" on the doorknobs in Ahmad Salem's Mosque, which was built in 1930 by Italian Architects and designers , reflects the influence of the Andalusian art on the Islamic buildings. many reasons could explain this influence as the historical and religious relationship between Andalusia and Alexandria by a lot of immigrants who came to the city and became the most famous Imams in the city, moreover  the Italian architects and designers who were managing the largest part of the construction business in Alexandria in first decade of twentieth century, their studies of the Islamic Art in their country before they move to Egypt, was concentrated on the Andalusian Art, cause of that their work in the Islamic religious buildings was influenced by the Andalusian art. But by a deep study in the meaning of the Motto ,and relating it with the conditions of constructing Ahmad Salem's mosque and with putting in consideration the rest of inscriptions in the mosque, it becomes clear that one of the main reason of using the Nasrid motto was a reflection of Ahmed Salem's status after building the mosque, showing and telling to everyone that the god helps everyone has a good intent, and he helped me in constructing this Mosque. Which means that this motto wasn't a just copied words and art  from Alambra palaces but it was chosen intentionally by the owner and the designer of the mosque.
