Saying Takbir (Allah Is Great Beyond Description) in the First Night of Shawwal

“Abu ‘Abdillah (a.s.) said to me, ‘On al-Fitr (first day of the month of Shawwal), there is Takbir (saying ‘Allah is greater than what can be described’), but it is concealed.’ I (the narrator) then asked, ‘Where is it?’ He (the Imam) replied, ‘It is during the night of al-Fitr, in Maghrib and the last ‘Isha’, and in the Fajr salat (prayer) and in the salat of ‘Id, and then it is cut-off.’ I then asked, ‘How do I say it?’ He replied, 'say, ‘Allah is the greatest (beyond description), Allah is the greatest, there is no god but Allah, and Allah is the greatest, Allah is the greatest, all praise belongs to Allah, Allah is greatest upon what He guided us.' This is in the words of Allah, the most Majestic and Glorious, “So you can complete the number’, (2:182) meaning, the fasts, ‘and that you should exclaim the Greatness of Allah for His having Guided you.” (2:185)
A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Asbat from Khalaf ibn Hammad a similar Hadith.

"You should say Takbir in the night of al-Fitr and in the morning of al-Fitr, just as you say Takbir during the tenth (day of the month of Dhu al-Hajjah).”

“I once said to abu ‘Abd Allah (a.s.), ‘People say that forgiveness descends upon the fasting people during the month of Ramadan in the night of destiny.’ He (the Imam) said, ‘O al- Hassan, al-Qarijar (a worker) receives his wages upon completion of his task on the night of ‘Id (first of Shawwal).’ I then said, ‘I pray to Allah to keep my soul in service for your cause, what then should we do?’ He (the Imam) said, ‘When it is sunset, take a shower, and when you complete al-Maghrib salat (prayer), raise your hands and say, “O Generous, O Benevolent, O Munificent, O the One who chose Muhammad and helped him, I appeal before You to grant salawat (favors and compensation to Muhammad and his family worthy of their services to Your cause). Forgive all of my sins that I have committed and You have counted against me, but I have forgotten them and they are before You in Your book.” Then bow down for prostration and say one hundred times, “I turn in repentance to Allah” while prostrating and ask for your wishes.’”

4. It is narrated that ’Amir al-Mu’minin, would perform two Rak‘at salat (prayer). In the first Rak‘at, he would read Chapter 1 and (then) 112 of the Holy Quran one thousand times. In the second Rak‘at, he would read Chapter 1 and 112 once only.
