Hadith.2034 - It is narrated by Sa'id al-Naqqash, who said: Abu Abdullah عليه السلام said to me:
"Indeed, there is Takbir (declaration of Allah’s
سبحانه وتعالى greatness) associated with Eid al-Fitr, but it is a recommended Sunnah."
Sa'id said: "I asked: Where is it to be performed?"
Imam
عليه السلام replied: "On the night of Eid al-Fitr during the Maghrib (sunset prayer) and the Isha (night prayer), during the Fajr (dawn prayer), and during the Eid prayer."
In another narration (not from Sa'id), it is also reported: "And during the Zuhr (noon prayer) and Asr (afternoon prayer), and then it ends."
Sa'id said: "I asked: How should I say it?"
Imam
عليه السلام replied: "Say: Allahu Akbar, Allahu Akbar, La ilaha illa Allah, wa Allahu Akbar, Allahu Akbar wa lillahi al-hamd. Allahu Akbar for what He has guided us to, and al-hamdulillah for what He has bestowed upon us."
This is the statement of Allah
سبحانه وتعالى, the Almighty and Majestic:
“And complete the prescribed period (of fasting), and glorify Allah for having guided you.” (Surah Al-Baqarah,
2:185).
