عَنْ مُجَاهِدٍ عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّهُ كَانَ يَلْعَقُ أَصَابِعَهُ ثُمَّ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِنَّكَ لَا تَدْرِي فِي أَيِّ طَعَامِكَ تَكُونُ الْبَرَكَةُ
Mujahid narrates that Sayyiduna Ibn Umar (may Allah be pleased with them both) used to lick his fingers and used to say that the Noble Prophet (peace and blessings be upon him) said: You do not know in which part of your food there is blessing.
