What is the ruling on not performing prayers in the the mosque, except for Friday prayer, despite having the time and ability to do so?

You must maintain congregational prayer because it is an obligation upon every able-bodied man, and your absence from it is not an excuse. Indeed, one of the objectives of Islamic law behind attending congregational prayer is to increase the number of Muslims and to attain great reward. The Prophet, peace and blessings be upon him, warned against falling behind from the congregation, saying: "There are no three people in the desert or in settled areas among whom the prayer is not established except that Satan gains mastery over them. So, adhere to the congregation, for indeed, the wolf eats the stray." Furthermore, jostling with men for the first row has great reward.
