Yes, the compiler did indeed cite, in one of his other works, an additional ḥadith; yet al-Ḥāfiẓ, in his reply to him, made it clear that it does not constitute evidence. I have reproduced al-Ḥāfiẓ’s words on this point in al-Ajwibah al-Nāfiʿah (p. 27); whoever wishes may consult it.

8 – Ḥadith (1176): “…The night prayer is two by two….”
I say: Its explanation appears in a version recorded by Muslim. It was said to Ibn ʿUmar—the narrator of the report—“What does ‘two by two’ mean?” He answered, “That one ends the prayer with the taslīm after every two rakʿahs.” A narrator is better informed about what he transmits than anyone else, all the more so when there are action-based reports showing that the Prophet ﷺ gave the taslīm after every two rakʿahs of the night prayer; you will find some of those in my book Ṣalāt al-Tarāwīḥ (1).

9 – Ḥadith 1231 already appeared under number 1201 (2) with extra wording, among which is the addition “wa jadda,” and this wording is found only in Muslim.

10 – Ḥadith (1439): “…in Ṣaḥīḥ Muslim … ‘or it reduces (aw yuḥiṭṭ).’” Al-Barqānī said: It was narrated by Shuʿbah, Abū ʿAwnah, and Yaḥyā al-Qaṭṭān from Mūsā—the same authority through whom Muslim transmitted it—and they all said “(yuḥiṭṭ)” without an alif.

I say: Nevertheless, Aḥmad related it in al-Musnad (1/180) from Yaḥyā—meaning al-Qaṭṭān—with the wording “aw yuḥiṭṭ,” exactly as in Muslim. He then added, “Ibn Numayr and Yaʿlā likewise said: ‘aw yuḥiṭṭ.’” This shows that al-Qaṭṭān was corroborated in this wording by Ibn Numayr and Yaʿlā, both of whom reported it from Mūsā.

Imam Aḥmad also transmitted it from the two of them in another place (1/185) through the narration of ʿAbd Allāh ibn
