Assalamu aalikom
It is obligatory for the man to pray in the masjed if he is able (meaning healthy) and if he is within a distance where he can hear the athan which is about 2 km.
Abu Hurayrah said that the Messenger of Allah (salla Allahu alahi wa sallam) said: “By the One in Whose hand is my soul, I had thought of ordering that wood be gathered, then I would command the call to prayer to be given, and I would appoint a man to lead the people in prayer, then I would go to men [who do not attend the congregational prayer] and burn their houses down around them. By the One in Whose hand is my soul, if anyone of you had known that he would receive a bone covered with meat or two (small) pieces of meat in a sheep’s foot, he would come for ‘Isha’ prayer.”
