The World Federation One Stop Fiqh

Ruling 1387

Based on obligatory precaution, recommended prayers cannot be performed in congregation in any situation; however, ṣalāt al‐istisqāʾ, which is performed to invoke rain, can be performed in congregation. The same applies to the prayers that were obligatory and have become recommended due to some reason, such as the Eid al-Fiṭr and Eid al-Aḍḥā prayers that were obligatory when the Imam (ʿA) was present and are recommended during his occultation.
