قَالَ أَمِيرُ الْمُؤْمِنِينَ ع الدُّهْنُ يُلَيِّنُ الْبَشَرَةَ وَ يَزِيدُ فِي الدِّمَاغِ وَ يُسَهِّلُ مَجَارِيَ الْمَاءِ وَ يُذْهِبُ الْقَشَفَ وَ يُسْفِرُ اللَّوْنَ[2].
“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin has said, ‘Applying oil softens the skin, increases the ability of brain, opens the channels of water, removes the scaling and makes color to glow.”’
