I read about a sahabi, possibly Abdullah ibn Umar, who would get off his mount when he went for Hajj/Umrah and act as if he was relieving himself, even though he had no need to relieve himself. Just pure imitation of the action. Because RasullAllah did it. If that doesnt carry the point across of how important it is to try to follow each and every aspect of the sunnah, then I am sure nothing else will.
