ما الحديث النبوي الذي يفرق بين صيام المسلمين وصيام أهل الكتاب، ومتى دخل الإسلام مصر؟

The difference between our fasting and the fasting of the People of the Book is the pre-dawn meal (suhoor), as the Prophet, peace and blessings be upon him, said: "The difference between our fasting and the fasting of the People of the Book is the eating of the pre-dawn meal." Islam entered Egypt in the year 20 AH.
