Hadith: If anyone of you eats, let him eat with his right hand, and if he drinks, let him drink with his right hand, for indeed the devil eats with his left hand and drinks with his left hand

عن ابن عمر رضي الله عنهما أن رسول الله صلى الله عليه وسلم قال:
«إِذَا أَكَلَ أَحَدُكُمْ فَلْيَأْكُلْ بِيَمِينِهِ، وَإِذَا شَرِبَ فَلْيَشْرَبْ بِيَمِينِهِ، فَإِنَّ الشَّيْطَانَ يَأْكُلُ بِشِمَالِهِ، وَيَشْرَبُ بِشِمَالِهِ».
[صحيح] - [رواه مسلم] - [صحيح مسلم: 2020]

Ibn ‘Umar (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"If anyone of you eats, let him eat with his right hand, and if he drinks, let him drink with his right hand, for indeed the devil eats with his left hand and drinks with his left hand."
[Authentic hadith] - [Narrated by Muslim] - [Sahih Muslim - 2020]

Explanation

The Prophet (may Allah's peace and blessings be upon him) enjoins that Muslims should eat and drink with their right hand and forbade eating and drinking with their left hand. This is because the devil eats and drinks with the left hand.
