31:19
وَ ٱقْصِدْ فِى مَشْيِ كَ وَ ٱغْضُضْ مِن صَوْتِ كَ إِنَّ أَنكَرَ ٱلْ أَصْوَٰتِ لَ صَوْتُ ٱلْ حَمِيرِ
And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys."
9:42
لَوْ كَانَ عَرَضًا قَرِيبًا وَ سَفَرًا قَاصِدًا لَّ ٱتَّبَعُ و كَ وَ لَٰكِنۢ بَعُدَتْ عَلَيْ هِمُ ٱل شُّقَّةُ وَ سَ يَحْلِفُ ونَ بِ ٱللَّهِ لَوِ ٱسْتَطَعْ نَا لَ خَرَجْ نَا مَعَ كُمْ يُهْلِكُ ونَ أَنفُسَ هُمْ وَ ٱللَّهُ يَعْلَمُ إِنَّ هُمْ لَ كَٰذِبُونَ
Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars.
