What is the ruling on attending congregational prayers (Salat al-Jama'ah), Friday prayers (Jumu'ah), and Eid prayers, given the spread of the coronavirus pandemic, taking into consideration the difficulty of distinguishing between infected areas, the long incubation period of the virus, and the ease of transmission through contact or inhaling sneezes?

The Sharia's concern for preserving health and preventing diseases necessitates caution against transmitting infection and intermingling with those afflicted by dangerous diseases. Ibn Taymiyyah permitted preventing a sick person from residing among healthy individuals, based on the hadith: "No sick person should be brought to a healthy one," and because the Prophet, peace and blessings be upon him, did not permit a leper to enter Medina.

Congregational prayers (Salat al-Jama'ah) and Eid prayers are not individually obligatory according to the majority of jurists, unlike Friday prayer (Salat al-Jumu'ah), which is an individual obligation for men unless there is an excuse. The question then is: Is illness considered an excuse for missing Friday prayer?

The answer varies depending on the reality of the situation and the anticipated harm, and the ruling is based on what is generally prevalent. A sick person is permitted to miss Friday prayer, and in some cases, it may be obligatory for them to do so. The assessment of harm and its probability of occurrence must be referred to specialists and health authorities, and an individual should not rely solely on their own personal judgment.
