Abu Ubaydah narrates that the (voluntary) daytime prayer of Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) was as follows: four rak'ahs before Zuhr, two rak'ahs after it, two rak'ahs after Maghrib, two rak'ahs after Isha, and two rak'ahs before Fajr; and he would not pray before Asr nor after it.
