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.
Tal será (a peregrinação). Quanto àquele que enaltecer os ritos sagrados de Deus, terá feito o melhor para ele, aos olhosdo seu Senhor. É-vos permitida a (carne) das reses, exceto o que já vos foi estipulado. Enviai, pois, a abominação daadoração dos ídolos e evitai o perjúrio,
Os que forjam mentiras são aqueles que não crêem nos versículos de Deus. Tais são os mentirosos.
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 ".
