الترمذي:٨٠١حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ حَدَّثَنَا أَبُو مُعَاوِيَةَ عَنْ سَعْدِ بْنِ طَرِيفٍ عَنْ عُمَيْرِ بْنِ مَأْمُونٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ قَالَ

قَالَ رَسُولُ اللَّهِ تُحْفَةُ الصَّائِمِ الدُّهْنُ وَالْمِجْمَرُ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ لَيْسَ إِسْنَادُهُ بِذَاكَ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ سَعْدِ بْنِ طَرِيفٍ وَسَعْدُ بْنُ طَرِيفٍ يُضَعَّفُ وَيُقَالُ عُمَيْرُ بْنُ مَأْمُومٍ أَيْضًا
