Ayesha reported,

Nothing was more hateful to the Messenger of Allah ﷺ than lying. A man might tell a single lie in his presence, and it would remain on the Prophet's mind until he came to know that the man had repented of it.

Azami 14885

Sahih

عن عائشة قالت

ما كان خلق أبغض إلى رسول الله ﷺ من الكذب، ولقد كان الرجل يكذب عنده الكذبة، فما تزال في نفسه حتى يعلم أنه قد أحدث منها توبة.
