حدثنا علي بن محمد حدثنا أبو معاوية حدثنا حجاج عن الحسن بن سعد عن ابن عباس
أن رسول الله ﷺ قرن الحج والعمرة

[Sahih] Ahmad narrated it, 28/4, from Abu Muawiya with this same wording. Busiri graded it daif because of the weakness of Ibn Artah and his tadlis, as mentioned earlier. Bukhari, 496, 1129, 2587. He was not the only one to narrate this report, as Anas bin Malik and others narrated something similar to it, see nos. 2968, 2969 and others. The individually transmitted (afrad) hadiths are more sahih. See Sunan al-Kubra by Bayhaqi, 169/5, and the response to that. And Allah knows best.
