Khutbah: The Address of Eidul-Adha
In this salah of Eid, Khutbah is a sunnah and is delivered after the salah, unlike the salah of Jumu'ah where it is fard and is delivered before the salah. However, listening to the khutbah of Eid salah is wajib or necessary and must be listened to in perfect peace and silence.
It is a sunnah that the Imam begins the first Khutbah by reciting takbir (Allahu Akbar) nine times and the second Khutbah with reciting it seven times.
The way of Eid prayer described above is according to the Hanafi school of Muslim jurists. Some other jurists, like Imam Shafi'i, have some other ways to perform it. They recite Takbir twelve times before beginning the recitations of the Holy Qur'an in both the raka'at. This way is also permissible. If the Imam, being of the Shafi'i school, follows this way, you can also follow him. Both ways are based on the practice of the Holy Prophet, Sall-Allahu alayhi wa sallam.
