اَللهُ اَكْبَرُ اَللهُ اَكْبَرُ اَللهُ اَكْبَرُ

aallh aakbar aallh aakbar aallh aakbar

Allah is the Greatest, Allah is the Greatest, Allah is the Greatest

In al-Oyoon: From Yasir al-Khadim and from Rayyan ibn Salt and others from those who narrated it from Abi al-Hasan al-Reza (a.s.) in a hadees:
When the (day of) eid came, Ma’mun sent for al-Reza (a.s.) asking him to ride to the eid prayer and give the sermon ... and when Ma’mun insisted, he (a.s.) said: O Ameer al-Moameneen , if you excuse me from this it will be more pleasing to me, and if you do not excuse me then I will come out for the eid prayer as the Prophet of Allah (s.a.w.a.) came out and as Ameer al-Moameneen Ali ibn Abi Talib (a.s.) came out ... so at sunrise al-Reza (a.s.) performed ghusl and wore a white turban made of cotton, placing one end of it on his chest and another end between his shoulders and said to all his slaves: “Do as I have done.” Then he took a short staff in his hand and came out and we were with him. He (a.s.) was barefoot, having rolled-up his trousers up to half the shank. When he stood and we walked in front of him, he raised his head toward the heavens and recited the takbeer four times ... and when he came to the door he stopped briefly and said:

عَلٰىمَا هَدَانَا اَللهُ اَكْبَرُ عَلٰى مَا رَزَقَنَا

eala ma hadana aallh aakbar eala ma razaqana

for that which He has guided us to. Allah is the Greatest for what He has granted us of sustenance

بَهِيْمَةِ الْاَنْعَامِ وَ الْحَمْدُ لِلهِ عَلٰى مَا اَبْلَانَا.مِنْ

min bahimat alaaneam w alhamd lilh eala ma aablana.

from the livestock, and all praise is due to Allah for what He has destined for us.

He recited this loudly and we also recited it loudly... and he said this three times... and Abu al-Hasan (a.s.) would walk and stop briefly after every ten steps, reciting the takbeer four times.
