When it was night and (a part of the night passed), Abud-Darda' got up (to offer the night prayer) but Salman asked him to sleep and Abud-Darda' slept. After some time Abud-Darda' again got up but Salman asked him to sleep. When it was the last hours of the night, Salman asked him to get up and both of them offered (Tahajjud) prayer.
