Ibn ‘Umar reported the Prophet ﷺ as sayings:
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.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي أَبُو بَكْرِ بْنُ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ جَدِّهِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ ﷺ قَالَ " إِذَا أَكَلَ أَحَدُكُمْ فَلْيَأْكُلْ بِيَمِينِهِ وَإِذَا شَرِبَ فَلْيَشْرَبْ بِيَمِينِهِ فَإِنَّ الشَّيْطَانَ يَأْكُلُ بِشِمَالِهِ وَيَشْرَبُ بِشِمَالِهِ " .
