Is it preferable for the revival of the time between the two 'Ishas with prayer to be in the mosque or at home, and which of them is better and brings greater reward?

Voluntary prayers (Nawafil) between Maghrib and Isha are desirable. It is preferable to perform them at home, like other supererogatory prayers, based on the Prophet's (peace and blessings be upon him) saying: "You should pray in your homes, for the best of a man's prayer is in his home, except for the obligatory prayer." Exceptions to this are the supererogatory prayers that are among the rituals of Islam, such as the two 'Eids, the eclipse prayer, the prayer for rain (Istisqa'), and Taraweeh, which have been legislated to be performed in congregation at the mosque.
