Every Friday, we go on an excursion to a place exceeding (81 km). We set out before the Fajr prayer, and when the time for Friday prayer arrives, a person stands and delivers a single moving sermon without the pillars and conditions of the Friday sermon. Then, he leads us in the two Rak'ahs of Friday prayer, and we join and shorten the 'Asr prayer with it. Is this action correct? And is the Friday prayer waived in the case of travel?
