Truth leads one to Paradise and virtue leads one to Paradise and the person tells the truth until he is recorded as truthful, and lie leads to obscenity and obscenity leads to Hell, and the person tells a lie until he is recorded as a liar.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الصِّدْقَ يَهْدِي إِلَى الْبِرِّ وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ وَإِنَّ الرَّجُلَ لَيَصْدُقُ حَتَّى يُكْتَبَ صِدِّيقًا وَإِنَّ الْكَذِبَ يَهْدِي إِلَى الْفُجُورِ وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ وَإِنَّ الرَّجُلَ لَيَكْذِبُ حَتَّى يُكْتَبَ كَذَّابًا  

Telling of truth is a virtue and virtue leads to Paradise and the servant who endeavours to tell the truth is recorded as truthful, and lie is obscenity and obscenity leads to Hell-Fire, and the servant who endeavours to tell a lie is recorded as a liar. Ibn Abu Shaiba reported this from Allah's Apostle ﷺ.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الصِّدْقَ بِرٌّ وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ وَإِنَّ الْعَبْدَ لَيَتَحَرَّى الصِّدْقَ حَتَّى يُكْتَبَ عِنْدَ اللَّهِ صِدِّيقًا وَإِنَّ الْكَذِبَ فُجُورٌ وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ وَإِنَّ الْعَبْدَ لَيَتَحَرَّى الْكَذِبَ حَتَّى يُكْتَبَ كَذَّابًا قَالَ ابْنُ أَبِي شَيْبَةَ فِي رِوَايَتِهِ عَنِ النَّبِيِّ ﷺ  

It is obligatory for you to tell the truth, for truth leads to virtue and virtue leads to Paradise, and the man who continues to speak the truth and endeavours to tell the truth is eventually recorded as truthful with Allah, and beware of telling of a lie for telling of a lie leads to obscenity and obscenity leads to Hell-Fire, and the person who keeps telling lies and endeavours to tell a lie is recorded as a liar with Allah.  

قَالَ رَسُولُ اللَّهِ ﷺ عَلَيْكُمْ بِالصِّدْقِ فَإِنَّ الصِّدْقَ يَهْدِي إِلَى الْبِرِّ وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ وَمَا يَزَالُ الرَّجُلُ يَصْدُقُ وَيَتَحَرَّى الصِّدْقَ حَتَّى يُكْتَبَ عِنْدَ اللَّهِ صِدِّيقًا وَإِيَّاكُمْ وَالْكَذِبَ فَإِنَّ الْكَذِبَ يَهْدِي إِلَى الْفُجُورِ وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ وَمَا يَزَالُ الرَّجُلُ يَكْذِبُ وَيَتَحَرَّى الْكَذِبَ حَتَّى يُكْتَبَ عِنْدَ اللَّهِ كَذَّابًا  

" He who endeavours to tell the truth and endeavours to tell a lie," and in the hadith transmitted on the authority of Mushir (the words are):" Until Allah records it".  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ فِي حَدِيثِ عِيسَى وَيَتَحَرَّى الصِّدْقَ وَيَتَحَرَّى الْكَذِبَ وَفِي حَدِيثِ ابْنِ مُسْهِرٍ حَتَّى يَكْتُبَهُ اللَّهُ
