The mobile phone footage, which is being widely shared on social media, shows Salah about to take a corner during the match at West Ham's London Stadium on Monday evening.
"When you have no concerns in your mind you are able to win a lot of times, that's how I felt when we were able to win at Dortmund".
Liverpool's lead at the top of the Premier League table was trimmed to three points after the Anfield club were held to a 1-1 draw by the Hammers, a result which dented the club's hopes of heaping more pressure on rivals Manchester City in the race for the title.
"I think that the organisation of this league and the respect in this league, for everyone, must continue to be a high standard".
"There is no doubt, it has been an unbelievable season for Liverpool up until now and it is right that they haven't had a bad spell in the season - we always say a team has that bit of a spell".
"We've got a good bunch and lot of big characters in the dressing room and we had a lot of experienced players on the pitch and the gaffer drills home that we need to play the same way, whether we're losing 1-0 or 2-0 or winning the game. Those stupid things, that must be punished as soon as you can".
A West Ham spokesperson condemned the Islamophobic behaviour and stressed a lifetime ban will be enforced should they identify the perpetrator.
In a statement, a West Ham spokesman said the club have a "zero tolerance policy" to any form of violent or abusive behaviour.
It continued: "We are an inclusive football club".
The Met police have since indicated that they are aware of the footage, which has since been circulated on Twitter, but that no arrests have been made.
