If you catch up with the Imam after he has stood up from Ruku`, this means that you have missed the Jumu`ah prayer. But if a person does not catch up with the prayer for a reason that is beyond his control, then there is no sin on him.

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.

Many hadiths have been narrated from the Prophet (peace and blessings of Allah be upon him) which explain the virtues of Jumu`ah prayer. Please see below.

1. Friday is a good day. There are many hadiths which speak of the virtues of Friday. 2. There are many acts of worship which are recommended for the Muslim to do on Friday such as offering Friday prayer, making a lot of du’a, sending a lot of blessings upon the Prophet Muhammad (peace and blessings of Allah be upon him) and reading Surat al-Kahf.
