I said: it indicates that there is another chain of transmission from Anas, and it is mentioned immediately after this with the wording "The first thing that will be asked..." and it will be discussed shortly. I said: and this chain is weak, and its defect is al-Qāsim ibn ʿUthmān, who was deemed weak by al-Bukhārī and al-Dāraqutnī. Then I found the ḥadīth was recorded by al-Ḍiyāʾ in "al-Mukhtārah" (209/2) through the route of al-Ṭabarānī: narrated to us by Aḥmad ibn Abī ʿAwf, narrated to us by Ismāʿīl ibn ʿĪsá al-Wāsiṭī through it. Then he narrated it through another route from al-Azraq through it. Then it was recorded by al-Ṭabarānī and al-Ḍiyāʾ (1/197) through the route of Rūḥ ibn ʿAbd al-Wāḥid al-Qurashī, narrated to us by Khalīd ibn Daʿlaj from Qatādah from Anas, raised to the Prophet with the wording: "The first thing a servant will be asked about on the Day of Judgment is his prayer; if it is sound, he will have succeeded, and if it is corrupt, he will have failed and lost." Al-Ṭabarānī said: "No one narrated it from Qatādah except Khalīd, and Rūḥ was unique in narrating it." I said: Abū Ḥātim said: "He is not strong." And Khalīd ibn Daʿlaj is weak. And he was contradicted by Abān ibn Yazīd al-ʿAṭṭār, who said: Qatādah informed us from al-Ḥasan from Anas, raised to the Prophet with it, except that he said: "he will have succeeded and prospered." It was recorded by Ibn Shādhān in "A Part of His Ḥadīth" (Q 16/1) from ʿUthmān ibn al-Sammāk, narrated to us by Aḥmad ibn Muḥammad ibn ʿĪsá al-Burtī, informed us by Mūsá ibn Ismāʿīl: informed us by Abān through it. And this isnād [chain of transmission] consists of trustworthy men from the "Tahdhīb" except for al-Burtī and ʿUthmān ibn al-Sammāk, who is ʿUthmān ibn Aḥmad ibn al-Sammāk, and both are trustworthy and mentioned in "Tārīkh al-Khaṭīb." If it were not for the ʿanʿanah [ambiguous transmission] of al-Ḥasan al-Baṣrī, I would have said it is a sound isnād. But it was recorded by Ibn Naṣr in "al-Ṣalāh" (Q 31/1), narrated to us by Muḥammad ibn Yaḥyá, narrated to us by Mūsá ibn Ismāʿīl through it, except that he said: from al-Ḥasan from Anas ibn Ḥakīm from Abū Hurayrah that the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said: and he mentioned it. Thus, the ḥadīth is from Anas ibn Ḥakīm
