they are to give; on ʿEid al-Aḍḥā he encourages them to offer the sacrifice and clarifies its ruling.

The extra takbīrs, the remembrance said between them, and the two sermons are Sunnah. It is disliked to perform voluntary prayers in that place either before the ʿEid prayer or after it. Whoever misses the prayer, or any part of it, is recommended to make it up in the same manner.

Unrestricted takbīr is recommended on the two nights preceding each ʿEid—more emphatically so for ʿEid al-Fiṭr—and throughout all ten days of Dhuʾl-Ḥijjah. Restricted takbīr, by contrast, is recited after every congregational obligatory prayer during ʿEid al-Aḍḥā¹, beginning with Fajr on the Day of ʿArafah, and for the pilgrim in iḥrām from Dhuhr on the Day of Sacrifice until the ʿAṣr of the last of the Days of Tashrīq. If one forgets it, he may make it up provided he has not invalidated his ablution or left the mosque. It is not Sunnah after the ʿEid prayer itself. Its formula, recited in pairs, is: Allahu akbar, Allahu akbar, la ilaha illa Allah; Allahu akbar, Allahu akbar, wa lillahi’l-hamd (Allah is supremely great, Allah is supremely great; there is no deity but Allah; Allah is supremely great, Allah is supremely great, and to Allah belongs all praise).
