Prayer: Can Shīʿas Pray Behind Sunnīs at Hajj Despite Differences in Maghrib Timing?

English:

Question #355:

Given that Sunnīs perform maghrib prayer before shar‘ī maghrib, is it permissible for us to perform prayers behind them during hajj season and at other times? Do these prayers suffice?

Answer #355:

It is not certain that their performance of prayer is before the arrival of its time. There is no problem in participating in their congregational prayer in order to maintain unity and avoid mischief-making. However, it is necessary to perform one’s prayer during its time unless the very time of prayer is a case for taqiyyah.
