Are the following situations considered excuses for not attending congregational prayer in the mosque: someone performing a task, riding a means of transportation, or accompanying a sick person in a clinic or hospital?

Congregational prayer in the mosque is not obligatory. Whoever prays in congregation at home or in another place has fulfilled the obligation, and there is no sin in not attending the congregational prayer in the mosque in the aforementioned cases. A person should strive to pray in congregation, such as praying with an employee he has or a companion during a doctor's visit. Whoever fears missing their companions is permitted to leave the congregation, and it is good if they pray in congregation after returning home.
