Haram Speech & character
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.
ذَٰلِكَ وَمَن يُعَظِّمْ حُرُمَٰتِ ٱللَّهِ فَهُوَ خَيْرٌۭ لَّهُۥ عِندَ رَبِّهِۦ ۗ وَأُحِلَّتْ لَكُمُ ٱلْأَنْعَٰمُ إِلَّا مَا يُتْلَىٰ عَلَيْكُمْ ۖ فَٱجْتَنِبُوا۟ ٱلرِّجْسَ مِنَ ٱلْأَوْثَٰنِ وَٱجْتَنِبُوا۟ قَوْلَ ٱلزُّورِ ﴿٣٠﴾
That [has been commanded], and whoever honors the sacred ordinances of Allah - it is best for him in the sight of his Lord. And permitted to you are the grazing livestock, except what is recited to you. So avoid the uncleanliness of idols and avoid false statement,
إِنَّمَا يَفْتَرِى ٱلْكَذِبَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِـَٔايَٰتِ ٱللَّهِ ۖ وَأُو۟لَٰٓئِكَ هُمُ ٱلْكَٰذِبُونَ ﴿١٠٥﴾
They only invent falsehood who do not believe in the verses of Allah, and it is those who are the liars.
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
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 ".
