 Another hadith explains that the primary haqq, upon which all other haqqs are based, is that “There is no god but God”, which is to say that there is nothing truly real but the Real, there is nothing truly right but the Right. In Islamic theology, understanding this notion is called tawhîd or “the acknowledgement of [divine] unity” and is considered the first of the three principles of faith; tawhîd also underlies the standpoints of the philosophers, even if some of them seldom spoke of God per se, preferring terms like the First, the Good, and the Necessary. This particular hadith tells us that God’s haqq against people (that is, their responsibility toward him) is for them to acknowledge tawhîd, and, if they do so, their right against God (his responsibility toward them) is for them to receive everlasting happiness, sa‘âda—the term philosophers used to translate eudaimonia.
