In Ramadan, is the Sawm (Fast)

Q 15: How long should the interval between Suhur (pre-dawn meal before the Fast) and Fajr (Dawn) Prayer be?

(Part No. 10; Page No. 334) A: The time of Suhur lasts until the time when Fajr Prayer is due because Allah (Exalted be He) says: ...and eat and drink until the white thread (light) of dawn appears to you distinct from the black thread (darkness of night) To the same effect, the Prophet (peace be upon him) said: Bilal announces the Adhan (call to Prayer) at night, so eat and drink until you hear the Adhan of Ibn Um Maktum. (Agreed upon by Al-Bukhari and Muslim.) Ibn Um Maktum was a blind man who would announce the Adhan only when he was told that dawn broke. However, it is Mustahab (desirable) to delay Suhur (until shortly before dawn).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
