One week after being forced off against Newcastle United with a worrying head injury, Murray swept home three minutes into the second half.
Mat Ryan made a key save from Ryan Bennett in second-half stoppage time as Brighton held on to record three successive wins in the top flight for the first time in 37 years.
Murray, who had a spell with Brighton from 2008 to 2011 before returning, initially on loan, in 2016, came in for effusive praise from Hughton after his landmark strike.
"He's somebody that is enjoying his football at the moment, he's scoring goals at the highest level," he told 'Sky Sports'.
"All of that is credit to him because of how he conducts himself, how he looks after himself, how he trains. You can't reach his age and play at this level without making those types of sacrifices."
