He did not forbid prayer except at the time of sunrise, for the sun rises between the two horns of Satan.
لم يكن ينهى عن الصلاة إلا عند طلوع الشمس، فإنها تطلع بين قرني الشيطان.
Imam Ahmad (23887) narrated it from Waki, from Shubah, from Qays bin Muslim, from Tariq bin Shihab, from Bilal, and he mentioned it. Tabarani also narrated it in Al-Kabir (1070) through the route of Shubah, likewise. Ibn Abu Shayba narrated it (2/354) through the route of Sufyan Thawri, from Qays bin Muslim, with the same chain, except that he mentioned in it "sunset" in place of "sunrise". Ruyani likewise narrated it in his Musnad (732) from the hadith of Sufyan with the same chain. So perhaps Bilal himself, on one occasion, narrated the prohibition "against prayer at sunrise", and so whoever heard this from him transmitted it accordingly, then he narrated the prohibition "against prayer at sunset", and so whoever heard this from him transmitted it accordingly. When the two are combined together, they produce the complete hadith, in agreement with the narration of others. Its chain of transmission is sahih, and Qays bin Muslim is al-Jadali, one of the narrators found in all the major collections.Haythami said in Al-Majma (3354), Ahmad and Tabarani narrated it in Al-Kabir with the same meaning, and the narrators of Ahmad are the narrators of the Sahih.His statement, "he did not use to forbid" is a passive-voice construction, and the one forbidding is the Prophet ﷺ.
