Answer:
(Fatwa: 516/382=L/1430)
It is not right to make a habit of performing salah at home with Jama?at. If by chance the salah of mosque is missed, one can perform it with Jama?at at home. By performing at home, one will get the reward of Jama?at but not that of mosque. Therefore, you should not make a habit of performing salah at home and convince your friend too to visit and perform the salah in mosque.
