It is narrated from ‘Amir bin Shahr who says: I heard one thing from the Noble Prophet (peace and blessings be upon him) and also heard one thing from Najashi. The Noble Prophet (peace and blessings be upon him) said: Look at the people of Quraysh, listen to their words, and leave their actions. He says: I was with Najashi when his son came carrying a book and he recited a verse from the Gospel and then explained it. I laughed. Najashi said: Do you laugh because of the Book of Allah? Listen! By Allah, indeed it is written in this Book which Allah revealed to ‘Isa that Allah’s curse will be upon this earth when its rulers are children (young boys).
