opening the first with nine takbirs and the second with seven in succession. (1)
Both sermons, the additional takbirs, and the remembrance said between them (2) are Sunnah.
It is disliked for the imam—or anyone praying with him—to offer supererogatory prayers at the place of the ʿEid prayer either before it or after it.
The unrestricted takbir, said aloud, is recommended throughout the two nights of the festivals—more emphatically on the night of ʿEid al-Fiṭr—and during each of the ten days of Dhu’l-Ḥijjah.
The restricted takbir, recited after every congregational obligatory prayer during ʿEid al-Aḍḥā, begins for residents from the dawn of the Day of ʿArafah, and for the pilgrim from the noon of the Day of Sacrifice until the afternoon of the last of the Days of Tashrīq.
If a person forgets it, he may supply it on the spot (3) so long as he has not broken wudūʾ or left the mosque; it is not prescribed after the ʿEid prayer itself.
Its wording—recited in pairs—is:
“Allahu akbar, Allahu akbar, lā ilāha illā Allah; Allahu akbar, Allahu akbar, wa lillāhi’l-ḥamd”
(Allah is greatest, Allah is greatest; there is no god but Allah. Allah is greatest, Allah is greatest, and to Allah belongs all praise).

Chapter: The Eclipse Prayer
The eclipse prayer becomes Sunnah whenever either of the two great lights—the sun or the moon—is eclipsed. It consists of two rakʿahs. In the first rakʿah he recites aloud Sūrat al-Fātiḥah and a long sūrah, bows for a long time, then rises saying: “Samiʿa-llāhu liman ḥamidah” and praises Allah. He then recites al-Fātiḥah again followed by another long sūrah shorter than the first, bows for a long time, though shorter than the first bow, rises and stands upright, and then prostrates twice for a lengthy duration. He performs the second rakʿah in the same manner as the first. (4)
