[Muslim].

Ibn `Umar (May Allah be pleased with them) reported: I performed along with the Messenger of Allah (sallallaahu ’alayhi wa sallam) two Rak`ah of optional prayers before Zuhr and two after the Zuhr (noon prayer), and two after the Friday prayer, and two after the Maghrib (evening) prayer, and two after the `Isha’ (night) prayer.”
