الآية رقم (78) - وَإِنَّ مِنْهُمْ لَفَرِيقًا يَلْوُونَ أَلْسِنَتَهُم بِالْكِتَابِ لِتَحْسَبُوهُ مِنَ الْكِتَابِ وَمَا هُوَ مِنَ الْكِتَابِ وَيَقُولُونَ هُوَ مِنْ عِندِ اللّهِ وَمَا هُوَ مِنْ عِندِ اللّهِ وَيَقُولُونَ عَلَى اللّهِ الْكَذِبَ وَهُمْ يَعْلَمُونَ

(78) - (And indeed, there is among them a party who alter the Scripture with their tongues so you may think it is from the Scripture, but it is not from the Scripture. And they say, "This is from Allah," but it is not from Allah. And they speak untruth about Allah while they know.)

They alter the Scripture, what Allah (swt) says, with their tongues to change its meaning. So, they used to alter the utterances and claim that they were part of what the Almighty (swt) said, although they are not so. However, they did that to underestimate Islam and challenge the Messenger (saws). Earlier, they said:

{ رَاعِنَا}

(Ra’ina.) (Al-Baqara: 104)

so, Allah the Almighty says addressing the believers:

 {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَقُولُوا رَاعِنَا وَقُولُوا انظُرْنَا وَاسْمَعُوا ۗ وَلِلْكَافِرِينَ عَذَابٌ أَلِيمٌ }

(O you who have believed, say not [to Allah ‘s Messenger], “Ra’ina” but say, “Unthurna” and listen. And for the disbelievers is a painful punishment.) (Al-Baqara: 104)

They also alerted (hitta) to (hinta) (in Arabic) to make us believe that such change is from the Scripture, but it is never so.
