If the day of `Eid coincides with Friday, then whoever prays `Eid with the Imam does not have to attend Jumu`ah but he has to pray Dhuhr.

Du`a by the Imam after an obligatory prayer – Jumu`ah or otherwise – with the congregation saying Ameen is something that was not done by the Messenger (blessings and peace of Allah be upon him) or by any of his Companions.

Allah chose Friday to be the best of days before Him and He singled it out for major events and great qualities. Jumu`ah prayer has a particular virtue and great qualities through the blessing of this great day.

There is nothing wrong with Muslims praying in a church if it is free of images and statues, whether that is the Jumu`ah prayer or any other prayer. It is disliked for Muslims to pray in a church if there are images or statues in it.

It is not permissible to combine `Asr with Jumu`ah in the cases where it is permissible to combine Dhuhr and `Asr. If a traveler passes through a town and prays Jumu`ah with them, it is not permissible for him to combine `Asr with it.
