Qaboos narrates from his father that his father sent a woman to Hazrat Aisha (may Allah be pleased with her) to ask which prayer the Prophet (peace and blessings be upon him) was most regular in performing. She replied that the Prophet (peace and blessings be upon him) used to pray four rak‘ahs before Zuhr, and he would stand for a long time in them, and perform bowing and prostration very well. And the prayer which the Prophet (peace and blessings be upon him) never abandoned, whether he was healthy or ill, present or traveling, was the two rak‘ahs before Fajr.
