This type of poetry has a fixed rhyme and the letter "ra" is the rhyming letter, and the vowel of the rhyme is the vowel of the meter, and the vowel before it is called the "tawkid". Their difference is called "al-ihaza".

And they say "al-ihara", and "al-ihara" is like the saying of the rajaz:

And he said: "When the night fell, and the cold intensified, and the days were cold."

And the opening of the "mim" is permissible in it, and the "kasra" before it is permissible because they alternate with the alternation of the "waw" and the "ba" in a single poem, such as "zuloom" and "raheem". Likewise, the "damma" and the "kasra" are more common in their poems, even if this meaning is in some of their poems. And they may warn against it, so they say:

"And the night was cold, and the days were cold."

And this is a doctrine that has been invalidated by consensus, as the narrations in the poems of the Arabs indicate that the "fatha" is permissible, and therefore the "tawkid" is not necessary, because the poet can direct it as he wishes with vowels. If it were not for the length, I would have provided evidence for it.

His saying "istalawoo" means they wore armor, which is the coat of mail. And it is narrated: "And the day was cold, and "al-sarr" is intense cold."

And his saying "and the day was cold" means it was cold.

And its meter is "qarr". And from the narration of "qarr" is that if sleep is scarce, and if it is cold, then the earth is burning.

And they pressed them with running, so that they almost burned from the intensity of the cold. What he said:

"And a day when those seeking warmth were burning in the sea."

And like the saying of Al-Ta'i:

"And a day when the high places protect their middle, and the souls are lost."
