A Bedouin once recited the following couplet:

البعرة تدل على البعير و آثار الأقدام على المسير
فسماء ذات أبراج و أرض ذات فجاج كيف لا تدل على اللطيف الخبير 

"When a lump of dung indicates that a camel had passed by and footsteps indicate that a person had passed by, then how could a sky filled with constellations and an earth crossed with paths not indicate the existence of the Creator who is most-gracious and all-aware?"

(Noorul Anwaar page. 173)
