1. Ali ibn Muhammad has narrated from Ahmad ibn abu ‘Abdillah from his father from Khalaf ibn Hammad from Sa‘id al-Naqqash who has said the following:

“Abu ‘Abdillah 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.
