308 أَنَّ رَجُلا أَكَلَ عِندَ رَسُولِ اللهِ -صَلَى الله عَلَيْهِ وَسَلَّمَ- بِشِمَالِهِ، فقالَ: كُلْ بِيَمِينِك، قال: لَا أَسْتَطِيع. قَالَ: لَا اسْتَطعْتَ، مَا مَنَعَهُ إِلَّا الكِبر فَمَا رَفَعَهَا إِلَى فيه
A man ate with his left hand in the presence of the Messenger of Allah (may Allah's peace and blessings be upon him), whereupon he said: "Eat with your right hand." The man said: "I cannot do that." Thereupon, he said: "May you not be able to do that." It was only arrogance that prevented the man from doing it, and consequently he could not raise it (his right hand) up to his mouth afterwards.

عن سلمة بن الأكوع رضي الله عنه : أن رجلا أكَلَ عند رسول الله صلى الله عليه وسلم بشماله، فقال: «كُلْ بيمينك» قال: لا أستطيع. قال: «لا استطَعْتَ» ما مَنَعَهُ إلا الكِبْر فما رَفَعَهَا إلى فِيهِ.

Salamah ibn al-Akwa‘ (may Allah be pleased with him) reported that a man ate with his left hand in the presence of the Messenger of Allah (may Allah's peace and blessings be upon him), whereupon he said: "Eat with your right hand." The man said: "I cannot do that." Thereupon, he said: "May you not be able to do that." It was only arrogance that prevented the man from doing it, and consequently he could not raise it (his right hand) up to his mouth afterwards.

صحيح - ( رواه مسلم ). Sahih/Authentic. [Muslim]

أكل رجل عند رسول الله صلى الله عليه وسلم بشماله تكبرا؛ فقال له النبي صلى الله عليه وسلم : "كل بيمينك" فقال في عِناد: لا أستطيع. وهو غير صادق في هذا؛ فدعا عليه النبي صلى الله عليه وسلم بقوله: "لا استطعت". فما استطاع أن يرفع يده إلى فمه، وذلك أنها أصيبت بشلل بدعاء النبي صلى الله عليه وسلم عليه؛ لتكبره ورده للأمر النبوي.
A man ate with his left hand in the presence of the Prophet (may Allah's peace and blessings be upon him) out of arrogance and vanity, so the Prophet (may Allah's peace and blessings be upon him) said to him: "Eat with your right hand." The man stubbornly said that he could not do that, and he was not truthful in his statement. Therefore, the Prophet (may Allah's peace and blessings be upon him) supplicated against him, saying: "May you not be able to do that." The man was never able to raise his right hand up to his mouth after that. The man's hand got paralyzed after supplication of the Prophet (may Allah's peace and blessings be upon him) against him because of his arrogance and rejection of the Prophet's command.

وجوب الأكل باليمين، وحرمة الأكل بالشمال من غير عذر. كُلُّ أمرٍ شريفٍ، ينبغي مباشرته باليمين وهذه قاعدة الشرع في الأمور المعظمة وفي باب الآداب. الاستكبار عن تطبيق الأحكام الشرعية يستحق فاعله العقوبة. إكرام الله لنبيه محمد -صلى الله عليه وسلم- بإجابة دعوته. جواز النصح للمرء على الملاْ إذا كان فيه خير للجميع.
