Brief Explanation
(Commentary on Hadith 2094)
From this hadith, the permissibility of eating various types of food and vegetables together is established.
The meaning of the narration of Ibn Majah (3324) is that cucumber, when eaten with dates, makes the body stout and is also delicious.
It is said that cucumber is cold (in temperament) and dates are hot, and they are corrective for each other, meaning the heat and intensity of dates is moderated by cucumber and melon.
