Question:
Hi,
Is a woman allowed to daven shachris before Neitz (but after alos)?
Answer:
If you won’t be able to daven otherwise then it is permitted, as it is also permitted for men, otherwise it is very b’dieved. It is also better to wait until after the time that men are allowed to put on their tefillin, because it is more light then.
