ANSWER:

This is authentic.

It must be 7 ajwa dates eaten early morning every day, specifically to protect from magic and poison. Whether it should be from Madina or not, this is an issue of dispute.

It seems to me that this is a speciality only for the Ajwah of Madina. 

Eating 7 ajwa dates a day prevents a person affected by poison and black magic. Is this hadees authentic?
