Shaykh Bin Baz was asked:
“I have a brother in Moscow and he is not able to pray the Friday prayer. We asked some Scholars of al-Azhar. They said that the Friday prayer is not obligatory in the lands of the disbelievers. Is there any evidence for that or do you take a view other than that
“Whatever the situation may be, it is not a must for the traveller to pray the Friday prayer for he prays dhuhr. But if he is staying a long time, then it is a must for him to pray the Friday prayer with the people, with the Muslims who are praying it. If he is in a land in which there is no Friday prayer and no one prays it, then he prays dhuhr and Friday prayer is not a must for him because prays dhuhr. As for if there are Muslims found, then he prays the Friday prayer. It is a must that he prays with them following them in it. He prays the Friday prayer with them. If such a situation is not found, then there is nothing upon him”. End translation.
Also Lajnah Ad Daimah was asked:
“Is Friday prayer obligatory upon us here while we are in the lands of the disbelievers?”
“Yes it is obligatory upon you to pray it with those who establish it from the Muslims with you.” End translation.
