This omission was not accidental. It is reported that Ibn Mas’ud said, "The two charm-Suras [113, 114] are not of the Book of God!" (www.Answering-Islam.org/Quran/Text/distortion.html)
Kuondolewa huko hakukuwa kwa bahati mbaya. Ilitaarifiwa kuwa Ibn Mas’ud alisema, "Hirizi mbili-Sura za [113, 114] si Kitabu cha Mungu." (www.AnsweringIslam.org/distortionInTheQuran.htm)
