I own a store and at prayer times,

Q: An institute of Islamic studies has now opened and it is offering great knowledge - all praise is due to Allah. The classes in the institute are in the evening after the (Part No. 8; Page No. 62) Maghrib (Sunset) Prayer until after the `Isha' (Night) Prayer. This means that we miss performing `Isha' Prayer with the first congregation and we perform it around two hours after the Adhan (call to Prayer). We also perform it in congregation, but after the first congregation. Please give me a Fatwa (legal opinion issued by a qualified Muslim scholar) as to whether I should attend these beneficial classes or perform the `Isha' Prayer with the first congregation? May Allah reward you with the best!

A: You should offer the `Isha' Prayer with the first congregation in the Masjid (mosque) and then resume the lessons after performing the Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
