2 – It is Sunnah for the fasting person to eat suhoor, because it was proven in al-Saheehayn that Anas ibn Maalik (may Allaah be pleased with him) said: The Prophet the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Eat suhoor for in suhoor there is blessing.” (Narrated by al-Bukhaari, 1923; Muslim, 1059).
3 – It is Sunnah to delay suhoor because of the report narrated by al-Bukhaari from Anas from Zayd ibn Thaabit (may Allaah be pleased with him) who said: “We ate suhoor with the Messenger of Allaah (peace and blessings of Allaah be upon him), then he got up to pray.” I said: “How much time was there between the adhaan and suhoor?” He said: “The time it takes to recite fifty verses.” (Narrated by al-Bukhaari, 1921).
Shaykh Ibn Baaz (may Allaah have mercy on him) said: “Suhoor is not a condition for fasting to be valid, rather it is mustahabb (recommended), because the Prophet (peace and blessings of Allaah be upon him) said: “Have suhoor, for in suhoor there is blessing.” (Agreed upon).
