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