The Messenger of Allah ﷺ said, "Whoever betrays the Arabs will not be included in my intercession, nor will my affection reach him."
قال أبو عبد الرحمن وجدت في كتاب أبي حدثنا محمد بن بشر حدثني عبد الله بن عبد الله بن الأسود عن حصين بن عمر عن مخارق بن عبد الله بن جابر الأحمسي عن طارق بن شهاب
قال رسول الله ﷺ من غش العرب لم يدخل في شفاعتي ولم تنله مودتي
Its isnad is daif. Husayn bin Umar Ahmasi is very daif. Ahmad accused him of lying, and Bukhari, Saji, and Abu Zura said his hadith is munkar. As for Abdullah bin Abdullah bin Aswad, Abu Hatim said, "A Kufan shaykh whose standing is that of truthfulness." Hafiz erred in Tahdhib 5:280 by transferring the coming statement of Tirmidhi about Husayn bin Umar and attributing it to this Abdullah instead. Makharaq Ahmasi is a trustworthy Kufan.The hadith was narrated by Tirmidhi 4:276, who said, "This is a gharib hadith. We know it only through the report of Husayn bin Umar Ahmasi from Makharaq, and Husayn is not considered particularly strong among the people of hadith."This hadith is one that Abdullah bin Ahmad found in his father's handwriting without having heard it from him, so he included it in the Musnad. Ahmad likely refrained from reading it aloud in the Musnad because of this severe weakness that you can see.
