Hamzah and alif of lengthening are not the same. Hamzah (ء) is an independent glottal consonant, whereas an alif of madd represents a long ā following fatḥah.
In أَمَرَ, the initial hamzah is a root radical.
In قَالَ, the medial alif is a long-vowel sign resulting from an underlying weak wāw radical.
Mahmūz classification requires radical hamzah; weak-root classification requires a weak radical. Confusing written alif and root hamzah leads to incorrect morphological analysis.
