the psak mentioned in the title is intriguing, but it was not directed at Jews. It was a "psak" issued by religious leaders in the Muslim world.

39 Muslim "poskim" signed on the new fatwah at a conference in Amman entitled "The road to Jerusalem".

The psak, or fatwah, says that visiting Har Habayit, Al Aqsa, is not a sign of normalizing relations with Israel, and anybody holding a European passport along with 450 million Muslims living outside of the Muslim countries, can, and should, go to visit Har Habayit. They explicitly annulled a previous fatwah that banned foreign Muslims from visiting Har Habayit under the guise that doing so would appear to be a normalization of relations with Israel.

how can we not lose this issue, when they visit, and call on their people to visit, Har Habayit, while we tell our people to stay away?
