It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that I heard a man reciting Surah Al-Ahqaf, and he was reciting it in a different manner. Another man was reciting it in another way, which was different from his companion, and I was reciting it in a third way, which neither of them were reciting. We went to the Prophet (peace and blessings be upon him) and informed him about this. The Prophet (peace and blessings be upon him) said: "Do not differ, for those before you were destroyed because of their differences." Then he said: "See who among you is the greatest reciter, and adopt his recitation."
