“I came to the Prophet (ﷺ) and in
front of him there were some bread and dates. The Prophet (ﷺ) said:
‘Come and eat.’ So I started to eat some of the dates. Then the
Prophet (ﷺ) said: ‘Are you eating dates when you have an
inflammation in your eye?’ I said: ‘I am chewing from the other
side.’
And the Messenger of Allah (ﷺ) smiled.”
Sunan Ibn Majah Book 31, Hadith 8
