The result keeps up the pressure on title rival Manchester City.
Salah, fresh from attending the Time 100 Gala in New York earlier this week, set up Naby Keita to open the scoring after just 15 seconds before finding the net himself on the stroke of halftime.
Sadio Mane grabbed a brace, scoring either side of Salah’s first strike with two expertly placed headers.
And the “Egyptian King” rounded off the scoring when he turned home Andy Robertson’s cutback in the 82nd minute to secure a 10th straight victory for Liverpool in all competitions.
That second strike was Salah’s 21st of the season in the Premier League, taking him to the top of the scoring charts, one ahead of teammate Mane and two ahead of City’s Sergio Aguero.
With just three weeks of the season remaining, Liverpool remain hopeful of a City slip-up that would hand them the advantage in the title race.
As it is, City can return to the top of the table should it defeat Burnley in its game in hand on Sunday.
