Ahruf is a word that signifies "dialects" but is translated as "letters." Allah revealed all Seven Ahruf to the Prophet (saw). They are all from the same Qur'an. None of the Ahruf's changes of words are contradictory; rather, they bring complexity and detail to the Qur'an. They are all from Allah, once again. Some examples of the variations among the Ahruf: In Surat Al-Fatiha, in the verse that says “The Owner of the Day of Judgement,” one of the Ahruf reads as "Maaliki Yawm Ad-Deen" مالك يوم الدين (meaning "Owner of the Day of Judgement"), and another reads as "Meliki Yawm Ad-Deen" ملك يوم الدين (meaning "King of the Day of Judgement") In Surat An-Noor, in the verse that speaks of “In Houses (Masajid) that were raised to remember Allah,” one of the Ahruf reads as “Buyut” بُيوت, and another reads as “Beeyut” بِيوت, which is simply a difference in dialect among the various Arab tribes and both have the same meaning.
