Ibn Hibban

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this statement of the Noble Prophet (peace and blessings be upon him): "Bilal gives the call to prayer during the night, so you may continue eating and drinking until Ibn Umm Maktum gives the call to prayer." Ibn Shihab states: Ibn Umm Maktum was a blind man. He would not give the call to prayer until it was said to him: 'The true dawn has come, the true dawn has come.' (Imam Ibn Hibban, may Allah have mercy on him, says:): This narration has been transmitted as a musnad (i.e., connected) hadith from Imam Malik only by Qanabi and Juwayriyyah bin Asma. All other students of Imam Malik have narrated that this narration is from Zuhri, from Salim, from the Noble Prophet (peace and blessings be upon him) (i.e., this is a mursal narration, not a connected one).
