al-Bayyinah— The Clear Proof

When pausing on مُطَهَّرَة al-Kisāʾī has two wajhs, fatḥ and imālah of the feminine hāʾ and the letter before it. The rāʾ before the hāʾ is one of the four letters (alif, kāf, hāʾ, rāʾ) whose imālah depends on what precedes them: it is inclined after a quiescent yāʾ or a kasrah, but after a fatḥah or ḍammah — as here, where the rāʾ follows the fatḥah of the doubled hāʾ — the imālah is the weaker wajh, so both fatḥ and imālah are transmitted. The four couplets give the whole rule: al-Kisāʾī inclines the feminine hāʾ at a pause except after the ten letters gathered in ḥaqqun ḍighāṭu ʿaṣin khaẓā; the four letters of akhar are inclined after a quiescent yāʾ or a kasrah (an intervening quiescent letter being no barrier) and only weakly after fatḥah or ḍammah; and everything other than the alif is inclined, according to some.
