What is the reason for the variation in the texts of the Gospel verses mentioned in Fatwa No. 111652 (Matthew 11:11-15 and Luke 7:26) compared to their texts in the circulated Gospels, and were these texts quoted from a specific book?

There are enormous differences among the Gospels due to distortion, alteration, additions by narrators, and variations among translators. Many works have addressed this aspect. The texts mentioned in the question from the Gospel of Matthew and the Gospel of Luke demonstrate these differences between various translations of the same Gospel.
