The bride's crown from Juwahir Al-Qamous 1/20

Taj al-Arus is considered one of the most important Arabic lexicographical encyclopedias, if not the most important of all, as it includes words from Al-Firuzabadi and corrects what was mistaken in it. It thus serves the Arabic language greatly. This edition was meticulously checked and accurately prepared. Orientalists say about it that it is the last linguistic extension in Arabic dictionaries, and after it, they stopped in this field. It is a dictionary that takes the endings of words, meaning it takes the last letter of the source of the word, then the first letter, then the second, following the same order as in Al-Qamus Al-Muheet. Al-Jabarti narrates a glimpse of how this remarkable work came to light, saying: "He began explaining Al-Qamus until he completed it over several years in about fourteen volumes, and he named it Taj al-Arus. When he finished it, he held a grand banquet gathering scholars and elders of the time at Ghayt Al-Ma'diya. That was in the year 1281 AH. He showed it to them, and they were pleased with it, witnessing its virtue, extensive knowledge, and solid foundation in the science of language. They wrote praises for it both in prose and poetry, including Sheikh Al-Kull in his era, Sheikh Ali Al-Saidi, Sheikh Ahmad Al-Dardir, Sayyid Abdul Rahman Al-Aydarus, Sheikh Muhammad Al-Amir, Sheikh Hassan Al-Jadawi, Sheikh Ahmad Al-Bayli, Sheikh Atiyah Al-Ajhoori, Sheikh Isa Al-Brawi, Sheikh Muhammad Al-Zayyat, Sheikh Muhammad Obada, Sheikh Muhammad Al-Awfi, Sheikh Hassan Al-Hawari, Sheikh Abu Al-Anwar Al-Sadat, Sheikh Ali Al-Qanawi, Sheikh Ali Khuraymat, Sheikh Abdul Qadir bin Khalil Al-Madani, Sheikh Muhammad Al-Maki, Sayyid Ali Al-Qudsi, Sheikh Abdul Rahman Mufti Jirja, Sheikh Ali Al-Shawri, Sheikh Muhammad Al-Kharbtawi, Sheikh Abdul Rahman Al-Maqri, Sheikh Muhammad Saeed Al-Baghdadi, known as Al-Suwaydi — he was the last to praise it. I was present then, writing it in verse spontaneously, in the middle of Jumada Al-Thani 1294 AH." When Muhammad Bek Abu Al-Dhahab established his famous library near Al-Azhar and created a book storage there, purchasing a collection of books and placing them there, they sent him this explanation of Al-Qamus, knowing that once placed in the library, its system would be complete, and it would be unique in that regard. They encouraged him to do so, so he requested it and was compensated with one hundred thousand silver dirhams, placing it there.
