(1) Manuscript *bāʾ* alone reads: “this.” (2) The words “in his *Sahīh*” are absent from manuscripts *nūn* and *mīm*. With some variation in wording, the hadith is narrated from Abū Hurayra—may Allah be pleased with him—in Muslim, 1/296–297 (Book of Prayer, chapter: The Obligation of Reciting al-Fātiha), and *Sunan al-Tirmidhī*, 4/269–270 (Book of Quranic Exegesis, Sura al-Fātiha). (3) Al-Suyūtī cited the hadith in *al-Jāmiʿ al-Kabīr*, 1/128, as follows: “The best words spoken by me and the prophets before me on the evening of ʿArafa are: ‘There is no deity worthy of worship except Allah alone, without partner. His is the dominion, to Him belongs all praise, and He has power over all things.’ Ismāʿīl ibn ʿAbd al-Ghāfir al-Fārisī included it in *al-Arbaʿīn* on the authority of ʿAlī.” Al-ʿAjlūnī cited the hadith in *Kashf al-Khafāʾ*, 1/153, saying: “The best supplication is that of the Day of ʿArafa, and the best words spoken by me and the prophets before me are: ‘There is no deity worthy of worship except Allah alone, without partner.’ Mālik narrated it in *mursal* form from Talha ibn ʿUbayd Allāh ibn Kurayz. Al-Tirmidhī also transmitted it from ʿAmr ibn Shuʿayb, from his father, from his grandfather, and graded it *hasan*, with the wording: ‘The best supplication is that of the Day of ʿArafa.’ He added: ‘His is the dominion, to Him belongs all praise, and He has power over all things.’ Al-Bayhaqī narrated it from Abū Hurayra with the wording: ‘The best supplication is that of the Day of ʿArafa, and the best words spoken by me and the prophets before me are: “There is no deity worthy of worship except Allah”’—and the remainder of the hadith. After ‘and to Him belongs all praise,’ he added: ‘He gives life and causes death, and all good is in His hand.’” I found that Mālik cited the hadith in *mursal* form, with the wording reported by al-ʿAjlūnī, in two places: 1/214–215 (Book of the Quran, chapter: Reports Concerning Supplication) and 2/422–423 (Book of Pilgrimage, chapter: General Matters Concerning Pilgrimage). The commentary states that Ibn ʿAbd al-Barr said: “All transmissions from Mālik agree that it is *mursal*. I know of no connected version with this chain through any route that may be used as proof. Reports concerning virtuous deeds do not require a chain that may be used as proof. It has, however, been narrated with a connected chain in the hadiths of ʿAlī and Ibn ʿAmr.” Al-Tirmidhī cited it with the wording reported by al-ʿAjlūnī in his *Sunan*, 5/231 (Book of Supplications, chapter: The Virtues of Saying, “There is no power and no strength except through Allah”). He said: “This is a *hasan gharīb* hadith through this chain. Hammād ibn Abī Humayd is Muhammad ibn Abī Humayd, who is Ibrāhīm al-Ansārī al-Madanī. Hadith scholars do not regard him as strong.” Shaykh Ahmad Shākir referred to the hadith in his notes on the *Musnad*, al-Maʿārif edition, 11/180. He stated that al-Mundhirī cited it in *al-Targhīb* through al-Tirmidhī’s narration and reported al-Tirmidhī’s grading of it as *hasan*. As for al-Bayhaqī’s narration of the hadith from Abū Hurayra, al-Suyūtī cited it, while al-Albānī graded it weak in *Daʿīf al-Jāmiʿ al-Saghīr*, 1/315.
