The sentence that begins with "cana" and its siblings Is it a noun phrase or verb phrase

His research deals with the grammarians 'opinion about the sentence that begins with "kan" and its siblings, is it a noun phrase or verb phrase? I went on in this research that the grammarians did not declare -as I read –if it is a noun phrase or verb phrase, except Ibn Hisham in his book, "Moghni al Labib" stated thatit is averb phrase .Some of the grammarians also went on to say that they are verbs that are not real, and called them verbs of the phrase.The research stats a view from one of the modern grammarians who said that the sentence which begins with "kan" and its siblings is a noun phrase, namely, Dr. Mohamed Hamasa Abdullatif, Saying what he relied on in this opinion in eight points.one point is, ibn Genie believed that it is not necessary to feminize "kan" for its name if it was feminine to the need for feminization of the verb for its subject if it was feminine.In this research, I believe that the sentence that begins with "kan", is a noun phrase, adding to what Mohammed Hamasa Abdul Latif said, which strengthens this opinion as the verb can settle for its subject. We can say: ( qam alrajul , wanam altifl) 'the man stands up.the child has slept'. It is not correct to say: Today the is cold, but yesterday was, without completing the sentence, say, for example: warm.
