The message was displayed on Tuesday the ninth day of Ramadan and attracted both complaints and praise from people.

The message quoted the Prophet’s saying, “All the sons of Adam are sinners but best of the sinners are those who repent it often.”

Network Rail announced that general Ramadan celebratory messages were not on display.

The department said the sign should not have been on the main train departure board and only should be used for exhibiting train information.

“We celebrate all the big religious festivals, from Christmas to Ramadan, at King’s Cross to reflect our diverse passenger and employee base,” a Network Rail representative told the BBC.

Public train stations “should not be urging ‘sinners’ to repent”, Humanists UK said in a post.

London iconic King’s Cross train station was built in 1851–52 and is part of popular culture, appearing in literature such as the Harry Potter series of books and films.
