عَنْ عَمْرِو بْنِ الْعَاصِ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ نَزَلَ الْقُرْآنُ عَلَى سَبْعَةِ أَحْرُفٍ عَلَى أَيِّ حَرْفٍ قَرَأْتُمْ فَقَدْ أَصَبْتُمْ فَلَا تَمَارَوْا فِيهِ فَإِنَّ الْمِرَاءَ فِيهِ كُفْرٌ
Sayyiduna Amr ibn al-As (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: The Noble Qur’an has been revealed upon seven modes of recitation; whichever mode you recite with, you will be reciting correctly. Do not dispute regarding it, for disputing about the Noble Qur’an is disbelief.
