(Fatwa: 1225/1225/M=01/1437)
According to Hanafi Fiqh it is makrooh to hold jamah of tahajjud or nafl with tada’i. Nafls such as Kusuf, Khusuf and taravih salah can be offered with jamah as it is proved. Jamah is not proved for tahajjud salah. It is also not desired for women to go to the mosques and participate in jamah with men. It is better for women to offer salah at home alone. Jumuah is not fardh on women. Hence women should avoid participating in tahajjud and Jumuah salah.
Allah knows Best!
