Its residents are fond of wearing silk and decorated and cheerful woolen textiles, of French and English make, and some of them believe they were made in Constantinople, and don't believe they were made in other countries, even if written so on them." Then he says: "The lands around Mecca seem barren, and it doesn't appear to grow anything, no greenery, gardens, or trees except for a few palm trees planted beside Zubaida's canal, and some shrubs. Mecca residents are characterized by courage and generosity and their houses are built on the slopes of the heights overlooking the Kaaba." Then he describes the Station (Maqam) and Zamzam well, the Holy Mosque and its gallery illuminated at night, the mosque courtyard, the seven minarets, and the number of the Mosque's forty gates and their names.
