Friday Prayer is obligatory upon every free, adult, sane, resident, adult male believer who has the ability to attend the salah and does not have a valid excuse to miss it. Salatul Jumuah however, is not obligatory on the following:

• Women.
  - Children.
  - The person who is ill and faces hardship if he goes to the mosque, or who fears that his illness will be increased by going to the mosque, or whose recovery will be delayed. This also includes the person who is nursing a very ill person, if especially, the ill person cannot manage in the absence of the nursing person.
  For the traveler.
• This is based on the fact that the Prophet (peace be upon him) traveled and did not perform the Friday Prayer but only prayed the Zuhr and `asr together during the time of the Zuhr prayers.
  Environmental restraints like extreme rain or cold, etc.

If one is traveling away from ones place of residence, the attendance of Jumuah prayer is not obligatory upon them in Shariah, but rather optional. If they attend the Friday prayer when traveling, they will receive a great reward from their Lord; and if for any reason whatsoever they abstain from it, there is absolutely no sin upon them.

To attend the Jumuah khutbah and prayer in congregation is obligatory upon every free, sane, resident, adult male believer who has the ability to attend the prayer and does not have an extremely valid excuse to miss it.
