Or that it is similar in name but different in taste; that is the second opinion (Parsing the word "mutashabih" and explaining the second opinion in His saying, the Exalted:

The Shaykh : It is a relief for the soul that it is one thing in appearance, but it differs in taste.
Imagine now that you have a plate in front of you containing fruit, which you think is one kind, but when you take each piece, you find it differs from the others. Yes, this is more delicious than if it were a single plate of one variety.
He says: "Or that it is similar" Yes, or that it is similar, is that how it is with you?
The student: Similar.

The Shaykh : Yes, if it is "similar" (mutashabih), then the author presented it in the form of a narrative (hikayah), and in the Qur'an it is in the accusative case, not the nominative? It is in the accusative case, so he presented it in the form of a narrative. If it is "similar" (mutashabih) in the nominative case, then he presented it in the form of parsing (i'rab), meaning: "similar" is the predicate of "that" (anna).
"Or that it is similar in name but different in taste; that is the second opinion"
The first is similar in color, and this is similar in name, but its taste differs. For example, pomegranates: the name is one, but the taste differs.
