Praise be to Allah.
The hadeeth is saheeh. It was narrated by Muslim in his Saheeh. It is to be interpreted, according to the scholars, as referring to people whose food includes dates, such as the people of Madeenah at the time of the Prophet (peace and blessings of Allaah be upon him) and others whose staple food is dates. And Allaah is the source of strength. End quote.
