It is reported of the Prophet  that he used to make takbeer (to say ‘Allahu ‘Akbaru ) in the two ‘Eid prayers in the first one seven times before the recitation, and in the second one five times before the recitation.

‘Al-‘Adawee said it was comely due to its testimonials, and that it was reported by ‘Ibn Majah, #1277; ‘Al-Hakim, #607/3; ‘Al-Bayhaqi, #288/3; ‘Ad-Darami, #376/1; and ‘Ibn Jarood, #262.
