Is it permissible to pray Isha after Tarawih, and is it permissible to pray Tarawih before Isha?

The performance of Ramadan prayers, known as "Tarawih prayer," takes place after the 'Isha prayer. If a Muslim prays with the congregation before 'Isha, their prayer is considered a supererogatory prayer (nafilah) between the two 'Isha prayers (Maghrib and 'Isha), and it is not the well-known Ramadan night prayer. The 'Isha prayer after that would be valid. It is preferable for a Muslim to begin with the obligatory prayer and then join them for Tarawih. If one prays with them with the intention of performing the obligatory prayer, then upon the Imam's salutation, one should stand and complete the obligatory prayer, and that would suffice. The important thing is that their prayer is valid and is considered a commendable supererogatory prayer between Maghrib and 'Isha.
