اَلْجَامِعَةِ 10:1

اَلذُّبَابُ ٱلْمَيِّتُ يُنَتِّنُ وَيُخَمِّرُ طِيبَ ٱلْعَطَّارِ. جَهَالَةٌ قَلِيلَةٌ أَثْقَلُ مِنَ ٱلْحِكْمَةِ وَمِنَ ٱلْكَرَامَةِ.

Dead flies cause the ointment of the apothecary to send forth a stinking savour: so doth a little folly him that is in reputation for wisdom and honour.
