When any of you eats, he should eat with his right hand, and when he drinks, he should drink with his right hand, for the devil eats with his left hand and drinks with his left hand.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ فَلْيَأْكُلْ بِيَمِينِهِ وَإِذَا شَرِبَ فَلْيَشْرَبْ بِيَمِينِهِ فَإِنَّ الشَّيْطَانَ يَأْكُلُ بِشِمَالِهِ وَيَشْرَبُ بِشِمَالِهِ  

The Prophet ﷺ said: Come near, my son, mention Allah's name, eat with your right hand and eat from what is next to you.  

قَالَ النَّبِيُّ ﷺ ادْنُ بُنَىَّ فَسَمِّ اللَّهَ وَكُلْ بِيَمِينِكَ وَكُلْ مِمَّا يَلِيكَ
