قَالَ أَمِيرُ الْمُؤْمِنِينَ ع غَسْلُ الْيَدَيْنِ قَبْلَ الطَّعَامِ وَ بَعْدَهُ زِيَادَةٌ فِي الْعُمُرِ وَ إِمَاطَةٌ لِلْغَمَرِ عَنِ الثِّيَابِ وَ يَجْلُو الْبَصَرَ[1].
“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin has said, ‘Washing hands before and after eating food removes stains from clothes and clears eyesight.’”
