وَعَن عُثْمَان بن عَفَّان قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ غَشَّ الْعَرَبَ لَمْ يَدْخُلْ فِي شَفَاعَتِي وَلَمْ تَنَلْهُ مَوَدَّتِي» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ لَا نَعْرِفُهُ إِلَّا مِنْ حَدِيثِ حُصَيْنِ بْنِ عُمَرَ وَلَيْسَ هُوَ عِنْدَ أهل الحَدِيث بِذَاكَ الْقوي

‘Uthman b. `Affan reported God’s messenger as saying, “He who is treacherous to the Arabs will not be included in my intercession and will not receive my love.” Tirmidhi transmitted it, saying this is a gharib tradition which he knew only among the traditions of Husain b. `Umar who is not considered by traditionsits to be strong.
