The Reds let a 2-0 lead slip in the draw at Leeds, with Salah an unused substitute for the game.
The previous two games had seen Salah come on as a substitute in a 1-1 home draw at Sunderland, while he was left on the bench in a 2-0 win at West Ham.
His last start was in a 4-1 defeat by PSV Eindhoven at Anfield in a Champions League group game and his last goal came in a 2-0 win at Aston Villa on Saturday, 1 November.
Salah has scored five goals in 18 appearances in the Premier League and Champions League this season.
Overall, he has 250 goals in 420 Liverpool appearances and his 29 top-flight goals in the 2024-25 campaign helped the Anfield side win the Premier League title last season.
Salah, who joined Liverpool from Roma in 2017, signed a new two-year contract with the club in April.
BBC Sport pundit and former England striker Wayne Rooney has said Salah is “destroying his legacy” at the club and said prior to the forward being left out of the Inter game that Slot should not involve him in Italy or for the home match against Brighton on Saturday.
“In my head, I’m going to enjoy that game because I don’t know what is going to happen now,” Salah said on Saturday.
“I will be in Anfield to say goodbye to the fans and go to Africa Cup of Nations. I don’t know what is going to happen when I am there.”
