The Messenger of Allah ﷺ said, "Whoever betrays the Arabs will not be included in my intercession, nor will my affection reach him."
حدثنا عبد بن حميد حدثنا محمد بن بشر العبدي حدثنا عبد الله بن عبد الله بن الأسود عن حصين بن عمر الأحمسي عن مخارق بن عبد الله عن طارق بن شهاب
قال رسول الله ﷺ من غش العرب لم يدخل في شفاعتي ولم تنله مودتي
[Its isnad is extremely daif] Ahmad narrated it, 1/72, from Muhammad bin Bishr, as his son Abdullah found it in his father's book, and this indicates that he did not narrate it in his Musnad. Husayn bin Umar is discarded (Taqrib).
