Leeds United have urged supporters to show respect when players who are observing Ramadan break their fast during Sunday's FA Cup fifth-round match against Norwich City.
Loud boos were heard when play was paused to allow fasting players to take on fluids and energy supplements during last weekend's match against Manchester City at Elland Road.
The club said the booing was "disappointing and unexpected", but added there were "several mitigating circumstances", including their own failure to properly explain the interruption to fans before it happened.
"To be clear, Leeds United explicitly condemn any supporters in the home or away sections who actively boo players observing Ramadan and use the protocol in place to break their fast," said the Premier League club in a statement issued on Friday.
Leeds said they should have been "more proactive with our communications in advance of the Manchester City fixture, to explain to supporters that this was going to happen", as "this was the first time a game at Elland Road has ever been paused to allow players observing Ramadan to break their fast".
The club added: "There was a clear lack of awareness by some attending the fixture. Whilst we displayed a message on our big screen at Elland Road to explain why the game had been paused, this was not visible for approximately 25% of the stadium."
As a further explanation to why some fans may have reacted as they did, Leeds pointed to an incident during the away fixture against Manchester City in November, when Farke accused goalkeeper Gianluigi Donnarumma of feigning injury to "bend the rules" and allow Pep Guardiola's side to hold a tactical timeout on the touchline.
Leeds say it is important "for respect to be shown" when the Norwich game pauses for players observing Ramadan to break their fast - including the club's striker Joel Piroe - following sunset on Sunday.
Sunset, which is when Muslims break their daily fast during Ramadan, is expected to fall around the 75th minute of a game that kicks off at 16:30 GMT.
Leeds also condemned discriminatory and tragedy chanting at football grounds, as well as continuing taunts referencing Leeds-born Jimmy Savile, one of the UK's most prolific sexual predators, aimed at the club's supporters by opposition fans.
"Football still has a long way to go in eradicating stains on the game, including racism, homophobia, tragedy chanting and the sickening Jimmy Savile taunts our own supporters are subjected to at every match from opposition fans," Leeds said.
"As a club, we will continue to work to ensure that in time, these issues cease to exist. On Sunday against Norwich City, there is an opportunity to show the very best of Leeds United, and that everyone is welcome at Elland Road."
