and al-Mundhirī (3/195) and al-Haythamī (8/168) said: "It was narrated by Aḥmad and al-Ṭabarānī in 'al-Kabīr' and 'al-Awsaṭ' and its men are trustworthy."

"If one of you catches the (first) prostration of the ʿAṣr prayer before the sun sets, let him complete his prayer. And if he catches the (first) prostration of the Fajr prayer before the sun rises, let him complete his prayer." It was narrated by al-Bukhārī in his "Ṣaḥīḥ" (1/148): Abū Nuʿaym told us, he said: Shaybān told us from Yaḥyā from Abū Salamah from Abū Hurayrah as a marfūʿ ḥadīth, without the two additions, which are found with al-Nasāʾī, al-Bayhaqī, and others. Al-Nasāʾī said (1/90): ʿAmr ibn Manṣūr informed us, he said: al-Faḍl ibn Dukayn narrated it. And this is a sound chain, for ʿAmr is a reliable and firm narrator as mentioned in "al-Taqrīb" and the rest of the men are known, and al-Faḍl ibn Dukayn is Abū Nuʿaym, al-Bukhārī's teacher in this, and both he and the narrator from him were followed in the two additions. As for ʿAmr, he was followed by Muḥammad ibn al-Ḥusayn ibn Abī al-Ḥunayn with al-Bayhaqī (1/368) and he said: "Al-Bukhārī narrated it in 'al-Ṣaḥīḥ' from Abū Nuʿaym al-Faḍl ibn Dukayn." And he means the original ḥadīth as is his habit, otherwise the two additions are not with al-Bukhārī as you know. As for Abū Nuʿaym, he was followed by Ḥusayn ibn Muḥammad Abū Aḥmad al-Marwadhī: Shaybān narrated it to us
