This hadeeth comes under the following chapter: DESIRABILITY OF OBSERVING THE MORNING PRAYER AT EARLIER HOUR AND THAT IS THE TIME WHEN THERE IS DARKNESS BEFORE DAWN AND THE INFORMATION REGARDING THE LENGTH OF RECITATION IN IT
Muhammad b. 'Amr b. al-Hasan b. 'All reported: When Hajjaj came to Medina we asked Jabir b. Abdullah (about the timings of prayer as observed by the Prophet). He said: The Messenger of Allaah (sallAllaahu alayhi wa sallam) used to pray afternoon prayer in the midday heat; the afternoon prayer when the sun was bright; the evening prayer when the sun had completely set; and as for the night prayer, he sometimes delayed and sometimes (observed it) at earlier hours. When he found them (his Companions) assembled (at earlier hours) he (prayed) early. and when he saw them coming late, he delayed the (prayer). and the morning prayer the Prophet of Allaah (sallAllaahu alayhi wa sallam) observed in the darkness before dawn.
