“They twist their tongues when reciting the Book so that you may suppose it is part of the Book, yet it is not part of the Book.” (Qur’an, 3:78)
The term “distortion” (taḥrīf) has been explained in two ways: distortion of the revealed wording itself (taḥrīf al-tanzīl) and distortion of its interpretation (taḥrīf al-taʾwīl).
Distortion of interpretation is extremely widespread, and many factions of this community have been tried by it. As for distortion of the revealed wording, that too has occurred among a number of people: they tamper with the Prophet’s actual phrases and transmit ḥadith in dubious forms. Although the seasoned critical scholars expose such forgeries, some go so far as to tinker with the Qur’anic text itself whenever they can, as when one of them recited: “And Allah spoke to Moses directly,” altering the verse’s construction.
Twisting the tongue with what is presumed to be from Allah also includes the fabricators who forge ḥadith and attribute them to the Messenger of Allah, peace and blessings be upon him, or those who advance what they imagine to be proof in religion when it is no proof at all. This category is one of the traits of the Jews, and its condemnation appears frequently to anyone who reflects on the Book of Allah and the Sunnah of His Messenger and then, by the light of faith, looks at the innovations that have arisen within the ummah.
