Yes. The Quran commands us to avoid false speech (22:30). The Prophet ﷺ said that truthfulness leads to righteousness and righteousness leads to Paradise, and that lying leads to wickedness.
Voilà [ce qui doit être observé] et quiconque prend en haute considération les limites sacrées d'Allah cela lui sera meilleur auprès de son Seigneur. Le bétail, sauf ce qu'on vous a cité, vous a été rendu licite. Abstenez-vous de la souillure des idoles et abstenez-vous des paroles mensongères.
Seuls forgent le mensonge ceux qui ne croient pas aux versets d'Allah; et tels sont les menteurs.
Hadith
Sahih al-Bukhari 6094
Narrated `Abdullah:The Prophet (ﷺ) said, "Truthfulness leads to righteousness, and righteousness leads to Paradise. And a man keeps on telling the truth until he becomes a truthful person. Falsehood leads to Al-Fajur (i.e. wickedness, evil-doing), and Al-Fajur (wickedness) leads to the (Hell) Fire, and a man may keep on telling lies till he is written before Allah, a liar
Arabic text (with chain of narrators)
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ الصِّدْقَ يَهْدِي إِلَى الْبِرِّ، وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ، وَإِنَّ الرَّجُلَ لَيَصْدُقُ حَتَّى يَكُونَ صِدِّيقًا، وَإِنَّ الْكَذِبَ يَهْدِي إِلَى الْفُجُورِ، وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ، وَإِنَّ الرَّجُلَ لَيَكْذِبُ، حَتَّى يُكْتَبَ عِنْدَ اللَّهِ كَذَّابًا ".
