حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْمَلِكِ بْنِ أَبِي الشَّوَارِبِ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ الْمُخْتَارِ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ:‏‏‏‏ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ إِذَا أَكَلَ أَحَدُكُمْ فَلْيَلْعَقْ أَصَابِعَهُ فَإِنَّهُ لَا يَدْرِي فِي أَيَّتِهِنَّ الْبَرَكَةُ ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ وَفِي الْبَاب عَنْ جَابِرٍ، ‏‏‏‏‏‏وَكَعْبِ بْنِ مَالِكٍ، ‏‏‏‏‏‏وَأَنَسٍ، ‏‏‏‏‏‏قَالَ أَبُو عِيسَى:‏‏‏‏ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ لَا نَعْرِفُهُ إِلَّا مِنْ هَذَا الْوَجْهِ مِنْ حَدِيثِ سُهَيْلٍ، ‏‏‏‏‏‏وَسَأَلْتُ مُحَمَّدًا عَنْ هَذَا الْحَدِيثِ، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ حَدِيثُ عَبْدِ الْعَزِيزِ مِنَ الْمُخْتَلِفِ لَا يُعْرَفُ إِلَّا مِنْ حَدِيثِهِ.

Narrated Abu Hurairah: That Messenger of Allah (ﷺ) said: When one of you eats, then let him lick his fingers, for indeed he does not know in which of them is the blessing. He said: There are narrations on this topic from Jabir, Ka'b bin Malik, and Anas. [Abu 'Eisa said:] This Hadith is Hasan Gharib, we do not know of it except from this route, as a narration of Suhail. I asked Muhammad about this Hadith, so he said: This is among the diverse narrations of 'Abdul-'Aziz, we do not know of it except from his narration.
