they worship Him and associate nothing with Him. Alongside this, the deed must also be righteous—that is, something Allah and His Messenger have commanded. This is obedience: every act of obedience is a righteous deed, and every righteous deed is an act of obedience. It is a deed prescribed by the religion and sanctioned by the Sunnah, for such deeds are commanded either as obligations or as recommendations. This is righteous action, goodness, piety, and virtue. Its opposite is disobedience, corrupt action, evil deeds, wickedness, evil, injustice, and transgression.
Now, every deed necessarily involves two things: intention and movement. As the Prophet, peace and blessings be upon him, said: “The truest names are Hārith [one who acts] and Hammām [one who intends].” Everyone acts and intends: everyone has deeds and intentions.
