For fourteen years, ‘Abdoos prayed the morning (Fajr) prayer with the [same] wudhoo [as he had prayed] the ‘Ishaa [prayer]. And he was the epitome of humility.
Asad ibn ‘Amr said that for forty years, Abu Haneefah prayed the ‘Ishaa [prayer] and the morning (Fajr) prayer with [the same] wudhoo.
Every day, my father would read a seventh [of the Qur.aan], and he would take a very light sleep after ‘Ishaa. He would then [awake and] stand [the night] in prayer and supplicate until the morning.
Abu Bakr al-Anbaaree said that al-Imaam, al-Haafith Abu ‘Ubayd would divide the night into thirds; so he would pray a third of it, and sleep a third of it, and author books [during] a third of it.
