The Messenger of Allah ﷺ taught me Surah al-Ahqaf, and he taught it to another man as well. The other man recited a verse differently from how I had learned it, so I asked him, "Who taught you this?"He answered, "The Messenger of Allah ﷺ taught it to me."I said to him, "But the Messenger of Allah ﷺ taught it to me in such-and-such a way."So I went to the Messenger of Allah ﷺ, and there was a man with him. I said, "Messenger of Allah, did you not teach me to recite it in such-and-such a way?"He replied, "Yes."The other man said, "Did you not teach me to recite it in such-and-such a way?"He replied, "Yes."The face of the Messenger of Allah ﷺ changed, then the man who was with him said, "Let each of you recite it as he heard it, for those before you were destroyed only because of their disagreements."I do not know whether the Messenger of Allah ﷺ commanded him to say this or whether it was something he said on his own.
حدثنا روح حدثنا حماد بن سلمة عن عاصم بن بهدلة عن زر بن حبيش
أقرأني رسول الله ﷺ سورة الأحقاف وأقرأها آخر فخالفني في آية منها فقلت من أقرأك قال أقرأني رسول الله ﷺ فقلت له لقد أقرأني رسول الله ﷺ كذا وكذا فأتيت رسول الله ﷺ وعنده رجل فقلت يا رسول الله ألم تقرئني كذا وكذا قال بلى قال الآخر ألم تقرئني كذا وكذا قال بلى فتمعر وجه رسول الله ﷺ فقال الرجل الذي عنده ليقرأ كل واحد منكما كما سمع فإنما هلك أو أهلك من كان قبلكم بالاختلاف فما أدري أأمره بذاك أو شيء قاله من قبله
