"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."
مَا كَانَ خُلُقٌ أَبْغَضَ إِلَى رَسُولِ اللَّهِ ﷺ مِنَ الْكَذِبِ وَلَقَدْ كَانَ الرَّجُلُ يُحَدِّثُ عِنْدَ النَّبِيِّ ﷺ بِالْكِذْبَةِ فَمَا يَزَالُ فِي نَفْسِهِ حَتَّى يَعْلَمَ أَنَّهُ قَدْ أَحْدَثَ مِنْهَا تَوْبَةً
