Is there a noble Hadith indicating that work is worship?

There are Hadiths indicating that permissible work undertaken to earn a livelihood, when intended as an act of obedience to Allah, transforms into an act of devotion for which its doer is rewarded. Thus, whoever goes out striving for their young children, or for elderly parents, or strives for themselves to keep themselves from begging or from unlawful acts, is in the path of Allah and will be rewarded for it. As for whoever goes out striving for show and boastfulness, they are in the path of Satan.
