عِفظيرُ إِنّا اِختَلَفنا

في الفِعلِ مِن فاعِلينِ

O clever one, we have differed

In the verb, between two agents

فَقالَ قَومٌ يُثَنّى

لِجَمعِنا الهَمزَتَينِ

Some said it gets dual inflection

To join the two hamzas therein

وَقالَ قَومٌ يُعَدّى

بِمُلتَقى الساكِنَينِ

Others said it gets passive inflection

Where two consonants meet within

وَأَنتَ أَعلَمُ مِنّا

بِذا وَذاكَ وَذَينِ

And you know better than we

About this, that, and therein

لِأَنَّكَ الدَهرَ فِعلٌ

يُعتَلُّ مِن جِهَتَينِ

For you, O time, are a verb

Imperfect from two sides
