Is it permissible to say Allaahu Akbar on the two `Eed in unison?

Question 476: In the southern towns, we recite the Takbeer (saying: “Allaahu Akbar [Allaah is the Greatest]”) in the Masjid (mosque) on `Eed as follows: Allaahu Akbar, Allahu Akbar, Allaahu Akbar, Kabeeran, wa al-hamdu lil laahi katheeran, wa Subhaana Allaahi bukratan wa aseelan, Laa Ilaahaa Illaa Allaah wahdah, Sadaq wa`dah, wa `Aza Jundah, wa Nasra `Abdah, wa Hazam Al-Ahzaba wahdah, laa ilaaha ill-Allaah, wa la N`budoo illaa-Iyah, Mukhlsin lahoo Al-Deen wa law Kariha Al-Kaafiroon, laa ilaaha ill-Allah, Allaahu Akbar, Wali-l-Laahi-l-Hamd (Allaah is the Greatest (thrice), there is no God but Allaah, and all Praise be to Allaah in abundance. Glory be to Allaah, morning and evening. He fulfilled His Promise, granted victory to His Slave and defeated the confederates Alone. We are sincere in Faith and devotion to Him, although the disbelievers detest it.) This Takbeer is recited aloud in unison until the call to commence Salaah (Prayer) is made. However, the Imaam stated that reciting Takbir in unison is impermissible and is a Bidd`ah (innovation in religion)? What is the ruling on this form of Takbeer?

Answer: Reciting Takbeer is Mashroo` (Islaamically acceptable) on the night and on the day of `Eed-ul-Fitr (the Festival of Breaking the Fast) before and after Salaah until the end of the Khutbah (sermon). It is also recommended during the first ten days of Dul-Hijjah and Days of Tashreeq (11th, 12th and 13th of Dul-Hijjah). The Sunnah is for each Muslim to recite it individually, but reciting it aloud as a group is a Bidd`ah. It was authentically narrated that the Prophet (peace be upon him) stated: Anyone who does an action which is not stated in this matter of ours (Islaam) will have it more here.
