(1) In the Z (ظ) and Mt (مط) copies the word “sabiq” (the winner) occurs in both instances, whereas the reading adopted here follows the H copy and the Musnad. (2) Musnad Ahmad 2:91, no. 5656; al-Bayhaqi, al-Sunan al-kubra 10:20 (a longer version), and others. The isnad runs through Qirad Abu Nuh and Hammad ibn Sulayman, both from al-Umari, from Nafiʿ, from Ibn ʿUmar: “The horses used to race over six miles, so the Messenger of Allah ﷺ gave a prize to the winner.” – wording of Hammad. I say: The clause “and he gave a prize to the winner” is peculiar, for ʿAbd al-Razzaq reports the same isnad from al-Umari, from Nafiʿ, with the wording found in the two Sahihs, omitting that phrase; see his Musannaf 5:304, no. 9695. The version of ʿAbd al-Razzaq is stronger: although Qirad is reliable, he has some solitary reports, and Hammad ibn Sulayman was deemed “unknown” by al-Bayhaqi. Moreover, ʿAbd al-Razzaq’s wording agrees with the transmissions of the major narrators from Nafiʿ—Malik, Ayyub, al-Layth ibn Saʿd, Musa ibn ʿUqbah, ʿUbayd Allah ibn ʿUmar (in his sound version), Juwayriyah, and others. Hence the phrase “and he gave a prize to the winner” is anomalous (shadh). Al-Zuhri is also reported to have said: “The first person to grant a prize for it was ʿUmar ibn al-Khattab.” Narrated by Ibn Abi Shaybah, al-Musannaf 6:531, no. 33537. See Talkhis al-habir 4:181. (3) Musnad Ahmad 3:160 and 256, nos. 12727 and 13689; also Ibn Abi Shaybah 6:532, no. 33547; al-Tabarani, al-Awsat 6:303, no. 8850; al-Tahawi, Mushkil al-athar 5:158, no. 1899; al-Daraqutni 4:301; and others. All routes go through Saʿid ibn Zayd—al-Zubayr ibn Khurayt—Abu Labid—Anas, who gives a longer version… Al-Tabarani commented: “No one narrates this hadith from Abu Labid except al-Zubayr ibn Khurayt,”
