(17) CHAPTER. The statement of the Prophet, peace be upon him, : The Adhan of Bilãl should not stop you from taking Sahür (late-night meals).
1918, 1919. Narrated ‘Aishah: Bilal used to pronounce the Adhan at night, so Allah’s Messenger, peace be upon him, said, “Carry on taking your meals (eat and drink) till Ibn Umm Maktum pronounces the Adhan, for he does not pronounce it till it is dawn.”
