Is the verb "أُعِدَّتْ" (has been prepared) in verse 131 of Surah Al Imran built in the passive voice to convey an image of the unseen Fire, which is unknown to man?

The exegetes did not mention the wisdom behind the passive construction of the verb "u'iddat" (was prepared) in the verse: "And fear the Fire which has been prepared for the disbelievers" (Qur'an 3:131). However, the omission of the doer (subject) has rhetorical reasons, among them:

1. Knowledge of the doer: Such as in "Man was created of haste" (Qur'an 21:37), where the intention is to inform about the occurrence of the action upon the object without needing to mention the doer. 2. Magnifying the doer: As in His saying: "The matter has been decreed concerning which you both inquire" (Qur'an 12:41), for the One who decreed it is of great power. 3. Suitability to the verse endings or what precedes it: Such as in "And no one has with him any favor for which recompense is to be given" (Qur'an 92:19) for suitability to the verse endings, and "And their hearts were sealed, so they do not understand" (Qur'an 9:87) for suitability to "And when a surah is revealed" which precedes it.

Thus, the verb "u'iddat" was constructed in the passive voice to magnify the Doer (Allah, Exalted be He) and due to knowledge of Him, and to emphasize His uniqueness in preparing the Fire. As for the claim that the reason is to convey the unseen image of the Fire to humans, it does not seem plausible.
