‘Abdur-Rahman bin Sa’d bin ‘Ammar bin Sa’d, the Mu’adhdhin
of the
Messenger of Allah (ﷺ), narrated from his father, from his
father,
from his grandfather, that the Messenger of Allah (ﷺ) used
to say
the Takbir in the ‘Eid prayer, seven times in the first
(Rak’ah)
before reciting Qur’an, and five times in the second
before reciting
Qur’an.
