Binadamu huyafanya matendo yake ili kutosheleza silika zake na mahitaji yake ya kiumbe. Kwa mfano, hutosheleza silika ya jinsia au uzazi (Ghareezat An-Naw’i) kupitia ndoa, hutosheleza silika ya kujihifadhi (Ghareezat ul-Baqaa’) kupitia umiliki wa mali, na silika ya kidini (Ghareezat At-Tadayyun) kupitia ibada. Hutosheleza mahitaji yake ya kiumbe kwa kula, kunywa na kulala, miongoni mwa matendo mengine kama hayo.

The human undertakes his actions in order to satisfy his instincts and organic needs. So for instance he satisfies his instinct of (human) kind or procreation (Ghareezat An-Naw’i) through marriage, he satisfies the survival instinct (Ghareezat ul-Baqaa’) through the ownership of property and the instinct of religiosity (Ghareezat At-Tadayyun) through acts of worship. He satisfies his organic needs by eating, drinking and sleeping amongst other such actions.
