By I couldn’t find any credible sources confirming that over 600 Europeans accepted Islam in a single day. While there have been reports of increased interest in Islam among Europeans, specific claims like this one lack verifiable evidence. For instance, a 2013 Reddit discussion referenced a 400% increase in European conversions to Islam, particularly in France, but lacked concrete data to support the claim.
Historically, Islam has spread through Europe over centuries, with significant growth during the 7th and 8th centuries. In modern times, the Muslim population in Europe has grown due to immigration and higher birth rates among Muslim communities. However, large-scale conversions in a single day are uncommon and not well-documented.
