I heard a man recite a verse differently from how the Messenger of Allah ﷺ had recited it to me, so I took him by the hand and brought him to the Messenger of Allah ﷺ.He said, "Both of you are doing well. Do not differ, for those before you differed and were destroyed."This is the best of my knowledge, otherwise it was Masaar who narrated it to me.
حدثنا عفان حدثنا شعبة أخبرني عبد الملك بن ميسرة قال سمعت النزال بن سبرة قال سمعت
سمعت رجلا يقرأ آية على غير ما أقرأنيها رسول الله ﷺ فأخذت بيده حتى ذهبت به إلى رسول الله ﷺ قال كلاكما محسن لا تختلفوا أكبر علمي وإلا فمسعر حدثني بها فإن من قبلكم اختلفوا فيه فهلكوا
Its chain of transmission is sahih. It is a repetition of 3724 and a fuller version appears at 3803. As for Shubah's statement "to the best of my knowledge," and so on, he means that his statement at the end of the hadith, "those before you differed and so perished," he strongly believes he heard from Abdul-Malik bin Maysara, and if he did not hear it from him directly, then he heard it from Misar bin Kidam on his authority. It has already been established at 3724 that Shubah heard it from Masaar from Abdul-Malik, so he set aside the doubt and relied on what he was certain of.As for "kilahuma" (both of them), it appears in kh as "kulahuma," and it has been corrected based on k.
