Hadith 568

Ibn Mas'ud said: I asked the Prophet which action is dearest to God and he replied, “Prayer at its proper time.” I asked what came next, and he replied that it was kindness to parents. I asked what came next and he replied that it was jihad in God's path. He said, “He told me of them, and if I had asked for more he would have told me more.” (Bukhari and Muslim.)
