Al-Adab Al-Mufrad, Book 55, Hadith 1296 (English) ⓘ
Al-Mughira ibn Shu'ba reported that a man said, "May Allah make the amir thrive! Your chamberlain recognises certain men and gives them preference in permission to enter." He said, "May Allah excuse him! Recognition helps with a voracious good and attacking camel."
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ: حَدَّثَنَا يُونُسُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ: قَالَ رَجُلٌ: أَصْلَحَ اللَّهُ الأَمِيرَ، إِنَّ آذِنَكَ يَعْرِفُ رِجَالاً فَيُؤْثِرُهُمْ بِالإِذْنِ، قَالَ: عَذَرَهُ اللَّهُ، إِنَّ الْمَعْرِفَةَ لَتَنْفَعُ عِنْدَ الْكَلْبِ الْعَقُورِ، وَعِنْدَ الْجَمَلِ الصَّؤُولِ.
