Sayyidah Aishah (may Allah be pleased with her) says that in the two Eids (prayers) the Messenger of Allah (peace and blessings be upon him) would say twelve takbirs besides the opening takbir, and he (peace and blessings be upon him) would recite (in the prayer) "Qaf. By the glorious Qur'an" and "The Hour has drawn near". This hadith was narrated by Abdullah bin Lahi'ah alone, and Imam Muslim cited him as a supporting narrator in two places. On this topic there are also narrations from Sayyidah Aishah, Ibn Umar, Abu Hurayrah and Abdullah bin Amr (may Allah be pleased with them), but their chains are weak. And according to one statement, Ibn Lahi'ah narrated it from Uqayl.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that in the two Eids the Prophet (peace and blessings be upon him) would say seven takbirs in the first rak'ah and five takbirs in the second rak'ah before the recitation.

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him), Abu Bakr and Umar (may Allah be pleased with them both) used to pray the two Eid prayers before the sermon. This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it with this wording; they recorded the hadith of Ata from Ibn Abbas in a different wording.

It is narrated from Sayyiduna Ali and Sayyiduna Ammar (may Allah be pleased with them both) that in the obligatory prayers the Prophet (peace and blessings be upon him) would recite "Bismillah al-Rahman al-Rahim" (In the name of Allah, the Most Gracious, the Most Merciful) aloud, and he (peace and blessings be upon him) would recite the qunut in the Fajr prayer, and he (peace and blessings be upon him) would begin the takbirs from the morning prayer of the day of Arafah and end them at the Asr prayer of the last of the days of Tashriq. This hadith has a sahih (authentic) chain, and I do not know of anyone among its narrators who has been criticised. On this topic there are also narrations from Jabir bin Abdullah and other Companions, while from Sayyiduna Umar, Ali, Ibn Abbas and Ibn Mas'ud (may Allah be pleased with them) saying the takbirs from the morning of the day of Arafah until the last of the days of Tashriq is authentically established. As for the narration about it from Umar:

Ubayd bin Umayr narrates that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) used to say the takbirs from after the Fajr prayer of the day of Arafah until the Zuhr prayer of the last of the days of Tashriq.

Shaqiq narrates that Sayyiduna Ali (may Allah be pleased with him) would begin saying the takbirat after the morning prayer on the Day of Arafah, and would not stop them until, on the last of the days of Tashriq, when the imam had prayed the (Asr) prayer, he would say the takbir after it as well.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he used to say the takbirat from the morning of the Day of Arafah until the Asr prayer of the last of the days of Tashriq.

Umayr bin Sa'id narrates that Sayyiduna Ibn Mas'ud (may Allah be pleased with him) came to us, and he used to say the takbirat from the Fajr prayer on the Day of Arafah until the Asr prayer of the last of the days of Tashriq.

Imam al-Awza'i (may Allah have mercy on him) was asked about the takbirat of the Day of Arafah, and he said: The takbirat are to be said from the morning of the Day of Arafah until the last of the days of Tashriq, just as Sayyiduna Ali and Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with them both) said them.

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) would come out (to the prayer ground) on the day of Eid al-Fitr and lead those two rak'ahs, then say the salam, then stand and face the people while they were seated, and he (peace and blessings be upon him) would say: "Give charity, give charity, give charity." The narrator said: Those who gave the most charity were the women, who would offer even their earrings and rings. [End of the Book of the Two Eids - Beginning of the Book of Witr]
