Assalamualaikum,
In our masjid Asr Jamat is according to Shafei so about half an hour to forty five minuites early and Isha Namaz is about fifteen minutes earlier than Shariah Board website using 18 degrees in calculation. There is no other masjid close by so can I pray both namaz with Jamat in his Masjid?
الجواب وباللہ التوفیق
In the described situation as the time for Salat doesn’t enter in view of the Hanafi School of Jurisprudence, one should not pray Salat at these times rather he should perform Salat with Jamat separately with his companions.
واللہ اعلم بالصواب
