What is the halakhic validity of learning before davvening shachris? Is this assur? Eating before davvening shachris is of course a problem (my understanding is that it really becomes a problem once you are a bar/bat mitzvah), but what about learning Gemara or Chumash before davvening? Is this permitted, and what sources indicate so? And is there any difference between learning before davvening during the week vs on Shabbes? Is there a maximum time that is allowed? My concern is with lessening bittl Torah and if I can get up to learn before davvening Shachris, that would be very helpful.
Thanks so much for your help.
