Yahya related to me from Malik from Ibn Shihab from Abu Bakr ibn Ubaydullah ibn Abdullah ibn Umar from Abdullah ibn Umar that the Messenger of Allah ﷺ said, "When you eat, eat with your right hand and drink with your right hand. Shaytan eats with his left hand and drinks with his left hand."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ فَلْيَأْكُلْ بِيَمِينِهِ وَلْيَشْرَبْ بِيَمِينِهِ فَإِنَّ الشَّيْطَانَ يَأْكُلُ بِشِمَالِهِ وَيَشْرَبُ بِشِمَالِهِ
