حدثنا أحمد بن سنان حدثنا كثير بن هشام حدثنا كلثوم بن جوشن القشيري عن أيوب عن نافع
قال رسول الله ﷺ التاجر الأمين الصدوق المسلم مع الشهداء يوم القيامة

[Daif] Reported by Hakim, 2/6, from the hadith of Kathir, in similar wording. Busiri said, "This chain contains Kulthum bin Jawshan, who is daif." It has a daif corroborating witness reported by Tirmidhi, no. 1209, and others, and Tirmidhi graded it hasan, but it contains flaws, including the fact that Hasan reported it using "an" (indicating an unspecified link), among other issues.
