Khubayb bin Abdur Rahman narrated from his paternal aunt, she heard the Prophet Muhammad (peace be upon him) say: Bilal (may Allah be pleased with him) gives the adhan at night, or Ibn Umm Maktum (may Allah be pleased with him) gives the adhan at night, so you should continue eating (the pre-dawn meal) until you hear the adhan of Ibn Umm Maktum or Bilal (may Allah be pleased with them). The only difference between the two was that one would descend (downstairs) and the other would ascend (to the roof). The narrator said: We used to say to them: Wait until we finish eating suhoor.
