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.
Ndio hivyo iwe! Na anaye vitukuza vitakatifu vya Mwenyezi Mungu basi hayo ndiyo kheri yake mbele ya Mola wake Mlezi. Na mmehalalishiwa nyama hoa ila wale mlio somewa. Basi jiepusheni na uchafu wa masanamu, na jiepusheni na usemi wa uwongo.
Wanao zua uwongo ni wale tu wasio ziamini Ishara za Mwenyezi Mungu. Na hao ndio waongo.
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 ".
