Is it permissible for my maternal aunt to pray Tarawih at home, following the imam of the nearby mosque, given the difficulty of her going to the mosque?

Scholars have differed regarding the validity of a follower praying behind an imam when the imam is in the mosque and the follower is in a house or similar place. Some permitted it, while others prohibited it. Therefore, it is more cautious for the woman not to pray behind this imam, to avoid the اختلاف (difference of opinion); her prayer performed individually is undoubtedly valid according to all scholars. As for her following him, it is a matter of scholarly disagreement. Congregation is not a condition for the validity of the Tarawih prayer.
