The Traveller is not obliged to offer the Friday Prayer
Question :
If a man missed the Friday prayer while on a journey, should he pray the two Rak'ahs as Friday prayer, or pray four Rak'ahs as Zuhr?
Answer:
The majority of the scholars hold that what he missed praying in congregation of the Friday prayer, he must pray as Zuhr. If he is a traveller who is entitled to shorten his prayers, then he may pray two Rak'ahs with the intention of Zuhr, reciting quietly therein. If he is a resident, then he must offer a four Rak'ah prayer, with the intention of Zuhr, reciting quietly therein. Some scholars disagreed with this, but the correct opinion is that held by the majority, because in the Farewell Pilgrimage, the Prophet stood at Arafah on a Friday and led the people in the Zuhr prayer and he did not lead them in the Friday prayer. Also, he did not order those living in the desert to perform the Friday prayer. And may peace and blessings be upon our Prophet, Muhammad.
