مَا كَانَ خُلُقٌ أَبْغَضَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم مِنَ الْكَذِبِ وَلَقَدْ كَانَ الرَّجُلُ يُحَدِّثُ عِنْدَ النَّبِيِّ صلى الله عليه وسلم بِالْكِذْبَةِ فَمَا يَزَالُ فِي نَفْسِهِ حَتَّى يَعْلَمَ أَنَّهُ قَدْ أَحْدَثَ مِنْهَا تَوْبَةً .
Aishah narrated:
"There was no behavior more hated to the Messenger of Allah than lying. A man would lie in narrating something in the presence of the Prophet, and he would not be content until he knew that he had repented."
Reported by At-Tirmidhi (No. 1973) and Ahmad (No. 24027).
