I would like to learn from sok after fajr till sunrise from home. Can I get rewarded for hajj and umrah if I pray after ishraq 2 rakat? Or is it mandatory to stay in the masjid till sunrise? ‏بارك الله فيكم

You have to remain in the place you prayed in (the masjid in your case) until sunrise, and you can study maybe from a phone or a tablet or so in sha'a Allah in the masjid from SOK.
