Abu Qais, who was the slave of Amr ibn al-As (may Allah be pleased with him), narrates that Sayyiduna Amr ibn al-As (may Allah be pleased with him) heard a man reciting a verse of the Noble Qur’an and asked:“Who taught you this verse?”He replied:“The Messenger of Allah (peace and blessings be upon him) did.”He (Amr) said:“The Messenger of Allah (peace and blessings be upon him) also taught me this verse, but in a different manner.”Both of them went to the Messenger of Allah (peace and blessings be upon him), and one of them said:“O Messenger of Allah! Such-and-such verse,”and then he recited it. The Prophet (peace and blessings be upon him) said:“It was revealed in this way (as you have recited).”The other said:“O Messenger of Allah!”and then he recited the same verse (in a different manner) and said:“O Messenger of Allah! Was this verse not revealed in the way I have recited it?”The Prophet (peace and blessings be upon him) said:“It was revealed in this way as well.”Then the Prophet (peace and blessings be upon him) (giving the final decision) said:“Indeed, this Noble Qur’an was revealed upon seven dialects; whichever dialect you recite in, you will be correct. (Just remember that) do not dispute regarding the Noble Qur’an, for such disputing is disbelief.”
