At-Tawbah 9:77

FaaAAqabahum nifaqan fee quloobihimila yawmi yalqawnahu bima akhlafoo Allaha mawaAAadoohu wabima kanoo yakthiboon

So He penalized them with hypocrisy in their hearts until the Day they will meet Him - because they failed Allāh in what they promised Him and because they [habitually] used to lie.

So Allah, in turn, put hypocrisy in their hearts till the day they shall meet Him, because they broke their promise with Allah, and because they have been telling lies.
