It is sunnah to pronounce the takbiraat on 'Eid day. Allah says "you should complete the prescribed period and that you should glorify Allah [i.e., say takbiraat] for having guided you and that you may give thanks." The majority of the scholars say that the time for the takbiraat during the eid is from the time one goes to the eid prayer until the khutbah begins. These takbiraat can be made in many different forms. The most authentic form is that which has been recorded f rom 'Umar and ibn Mas'ud - 'Allahu akbar. Allahu akbar. La ilaha illallah. Allahu akbar. Allahu akbar wa lillahil-hamd.' Translation:
Allah is the greatest, Allah is the greatest. There is no God but Allah. Allah is the greatest, Allah is the greatest. All praise belongs to Allah.
