Hadith.1926 - It is narrated from Isa ibn Abi Mansur, who said
"I was with Abu Abdullah (as) on the day when people were uncertain (whether it was the first of Month of Ramadan or not).
Imam (as) said: 'O boy, go and see whether the Amir (ruler) has fasted or not.'
The boy went and returned, saying: ''No, he has not fasted.'
Then Imam (as) called for lunch, and we ate with him."
