And be modest in your bearing being moderate in it neither dragging slowly nor rushing but peaceful and dignified and lower your voice; indeed the most hideous of voices is the donkey’s voice’ beginning its hideous bray with an exhalation and ending with an inhalation.
- 31:1919
وَاقْصِدْ فِي مَشْيِكَ وَاغْضُضْ مِنْ صَوْتِكَ ۚ إِنَّ أَنْكَرَ الْأَصْوَاتِ لَصَوْتُ الْحَمِيرِ
Be moderate in your bearing, and keep your voice low. Surely the most repulsive voice is the donkey's."
