Q: Is Friday prayer obligatory? What about someone who do not participate in it intentionally?
A: Friday prayer is considered an alternative obligation during this period of time that the infallible Imam( may Allah hasten his reappearance) is not present. One has the choice to perform either Friday or zuhr prayer although it is preferred to say Friday prayer and it is religiously dispraised when one does not attend or participate in this religious and political prayer out of not considering it important.
