Ahmad 7216

Its isnad is sahih. Saeed is Ibn Abu Aruba. Khilas, with a kasra on the dotted kha and a light lam, is Ibn Amr Hijri. His reliability was already established at 4099, and we add here that Ibn Saad gave his biography in Tabaqat 1/7/108-109, and Ibn Abu Hatim in Jarh wal-Tadil 1/2/402-403. It is reported from Abdullah bin Ahmad, from his father, who said, "Khilas is trustworthy, trustworthy." Ajli said, "A trustworthy successor." He narrates from Abu Hurairah directly, and he also narrates from him through an intermediary, as in this hadith.It will come at 10344 from Muhammad bin Jafar and Rawh, both of them from Saeed bin Abu Aruba with this isnad.Bayhaqi related it in Sunan al-Kubra 1:379, via Rawh, from Saeed bin Abu Aruba with this isnad, in similar wording.Hakim related it in Mustadrak (1:274), via Hammam, from Qatada, with this isnad, with the wording, "Whoever prays one rakat of the dawn prayer, and then the sun rises, let him complete his prayer."He had related before that, in similar wording, via Hammam, from Qatada, from Nadr bin Anas, from Bashir bin Nuhayk, from Abu Hurairah, as a raised hadith.Then he said, "Both isnads are sahih, for both of them relied on Khilas bin Amr as a corroborating witness." Dhahabi agreed with him that it meets the standard of the Sahihayn.Bayhaqi also related, at 1:379, via Affan, "Hammam narrated to us, he said, Qatada was asked about a man who prayed one rakat and then the edge of the sun rose. He said, Khilas narrated to me, from Abu Rafi, that Abu Hurairah told him that the Prophet ﷺ said, 'He completes his prayer.'"It will come again, through the routes by which Hakim and Bayhaqi related it, at 8042, 8551, 10364, 10761.Bukhari related something similar in meaning, together with the Asr prayer, at 2:32, from the narration of Abu Salama, from Abu Hurairah.The basic meaning is established in the Sahihayn, through various routes from Abu Hurairah, including in Bukhari 2:46, and Muslim 1:168-169.See also Muntaqa 601, 602.The basic meaning will come again in the Musnad many times, through various routes from Abu Hurairah, including 7451, 7529, 9955, 10133.His saying, "let him pray another one added to it (alayha)." This is how it appears in manuscripts H and M. In manuscript K it reads "ilayha" instead of "alayha," which agrees with the rest of the narrations containing this wording that we have referred to.
