Is it permissible to pray Maghrib before its time due to work and commuting circumstances that lead to its time expiring and the time for Isha entering upon arriving home?

The Maghrib prayer is not permissible before its time (sunset), and if it is performed before then, it is invalid, and repentance and re-performance are required. Similarly, it is not permissible to delay Maghrib until the time for 'Isha' enters, except for a legitimate excuse such as travel, illness, or rain. Arriving home after the 'Isha' prayer time has begun does not permit delaying it unless there was an inability to stop and perform the prayer at its designated time.
