There is another route for this, recorded in "al-Janāʾiz" (136-137) and "al-Irwāʾ" (no. 760). The first part of the ḥadīth was attributed by al-Ḥāfiẓ in "al-Fatḥ" (4/234) to Aḥmad, and he remained silent about it, indicating his strengthening of it. It has supporting evidence, some of which was previously mentioned under numbers (980, 981, and 1014), and it clearly indicates that it is not permissible to fast it alone, even if it coincides with a virtuous day like ʿĀshūrāʾ or ʿArafah, contrary to al-Ḥāfiẓ. I have elaborated on this previously, and see ḥadīth (2398).

The addition is by al-Bukhārī, Ibn Ḥibbān in his narration (5787), Aḥmad, and al-Bayhaqī, as well as Ibn Ḥibbān in his narration (5785) and al-Tirmidhī, but in a shortened form: "and he is named: Muḥammad Abū al-Qāsim." He said: "A ḥadīth that is ḥasan ṣaḥīḥ." I say: It is as he said, for its isnād is ḥasan, and it has a witness from the ḥadīth of Sufyān from ʿAbd al-Karīm al-Jazarī from ʿAbd al-Raḥmān ibn Abī ʿAmrah from his uncle, marfūʿ, without the addition
