TELLING THE TRUTH AND LYING H 55 "Truth guides to virtue and virtue guides to Paradise. A person who continuously tells the truth is called truthful in the Sight of Allah. Lying leads to vice and vice leads to the Fire; when someone lies continuously in the Sight of Allah that person is called a liar." R 55 Bukhari and Muslim with a chain up to Abdullah son of Mas'ud who related the Messenger of Allah said this.
54- وأما الأحاديث فالأول : عن ابن مسعود رضي الله عنه ، عن النَّبيّ صلى الله عليه وآله وسلم ، قَالَ : "إنَّ الصِّدقَ يَهْدِي إِلَى البرِّ ، وإنَّ البر يَهدِي إِلَى الجَنَّةِ ، وإنَّ الرَّجُلَ لَيَصدُقُ حَتَّى يُكْتَبَ عِنْدَ اللهِ صِدِّيقاً . وَإِنَّ الكَذِبَ يَهْدِي إِلَى الفُجُورِ ، وَإِنَّ الفُجُورَ يَهدِي إِلَى النَّارِ ، وَإِنَّ الرَّجُلَ لَيَكْذِبُ حَتَّى يُكتَبَ عِنْدَ الله كَذَّاباً" مُتَّفَقٌ عَلَيهِ .
