Notes & justification
The rhyming āyah-endings of Sūrat aḍ-Ḍuḥā (all of them alif maqṣūrah): al-Kisāʾī gives every one of them imālah; Warsh and Abū ʿAmr (al-Baṣrī, both his rāwīs) give every one taqlīl; Ḥamzah and Khalaf al-ʿĀshir give them all imālah except سَجَىٰ, which they read with fatḥ. The couplets: Ḥamzah and al-Kisāʾī incline the alifs that go back to a yāʾ; al-Kisāʾī alone inclines أَحْيَا after a wāw, تَلَاهَا, طَحَاهَا, سَجَىٰ and دَحَاهَا (words of wāw origin), while ضُحَاهَا, ٱلضُّحَىٰ, ٱلرِّبَا and ٱلْقُوَىٰ they both incline; and among what they incline are the āyah-endings of eleven sūrahs — Ṭāhā, an-Najm, ash-Shams, al-Aʿlā, al-Layl, aḍ-Ḍuḥā, al-ʿAlaq, an-Nāziʿāt and the rest named — which is why every fāṣilah here but سَجَىٰ carries Ḥamzah's imālah.
Ḥamzah among them, and al-Kisāʾī after him, both incline the words of yāʾ origin wherever that origin is established.
But aḥyā, after its wāw, is from both of them; in the other occurrences it is inclined for al-Kisāʾī alone.
And the word talāhā with ṭaḥāhā, and in sajā, and the word daḥāhā — these are of wāw origin (and inclined for al-Kisāʾī).
As for ḍuḥāhā, aḍ-ḍuḥā, ar-ribā and al-quwā, both inclined them, though they are of wāw origin.
Among what both inclined are the endings of the āyāt in Ṭāhā and an-Najm, so that the endings are kept alike.
And in ash-Shams, al-Aʿlā, al-Layl and aḍ-Ḍuḥā, in Iqraʾ and in wa-n-Nāziʿāt, they are inclined.
