For example: احتَفَلَ الجمعُ احتفالاً عظیما ً (The group rallied, a great rally.

For example: احتَفَلَ الجمعُ احتفالاً عظیما ً (The group rallied, a great rally.) becomes احتُفِلَ احتفالٌ عَظیم ٌ (A great rally was rallied.) The preterite tense passive verb is made from the preterite tense active verb by giving a kasrah to the second to last letter and a dummah to all other letters that have a vowel sign already. For example: أکَلَ (he ate) becomes أُکِلَ (it was eaten) or اِستَقَبَلَ (he faced) becomes اُستُقبِلَ (it was faced).
