Narated By U’adh : They (the Companions) proceeded on the expedition of Tabuk along with the Apostle of Allah (PBUH). He combined the noon and the afternoon prayers and the sunset and night prayers. One day he delayed the prayers and came out of his dwelling and combined the noon and the afternoon prayers. He then went in and came out and combined the sunset and the night prayers.
