Ibn Mas'ud (May Allah be pleased with him) reported: I asked the Messenger of Allah (PBUH): "Which act is the best?" He (PBUH) said, "As-Salat at their fixed times." I asked, "What next?" He (PBUH) said, "Being dutiful to parents." I asked, "What next?" He (PBUH) said, "Striving (Jihad) in the way of Allah."
