حَدَّثَنَا مُوسَى بْنُ عَبْدِ الرَّحْمَنِ، أَنْبَأَنَا أَبُو دَاوُدَ الْحَفَرِيُّ، عَنْ سُفْيَانَ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لاَ يَمْسَحْ أَحَدُكُمْ يَدَهُ حَتَّى يَلْعَقَهَا فَإِنَّهُ لاَ يَدْرِي فِي أَىِّ طَعَامِهِ الْبَرَكَةُ " .
It was
narrated from Jabir that the Messenger of Allah (ﷺ) said: “None
of you should wipe his hand until he has licked it, for he does
not
know where the blessing if in his food.’”
Sunan Ibn Majah 3270
