Hazrat Ali told knowledge is power...

By increasing knowledge. Knowledge is power.

There are several definitions, such as knowledge is power, but my definition is that knowledge is the understanding of information in life.

Simply, an idiot. Knowledge is power.

The quote "Knowledge is power" is attributed to Sir Francis Bacon, an English philosopher and statesman from the 16th century. He believed that knowledge and education were essential for personal growth and societal progress.
