History is filled with intriguing events that require a researching eye to unveil their strangeness, as Ibn Abi Hajla Al-Tilmisani did by following the number '7' in the history of Egypt, its sultans, and kings. This exploration extended to its role in the stories of the prophets Yusuf and Musa, peace be upon them, alongside the connection to Egypt, Cairo, and surrounding regions related to this number.

However, Sultan Hasan bin al-Nasir Qalawun and his family received special attention with multiple chapters dedicated to them, especially regarding the number '7'. The book is also enriched with poetry at the end of each chapter, making it a small yet significant historical and literary treasure.
