Haram Speech & character
Yes. The Quran warns against breaking oaths after making them firm (16:91), and warns those who sell Allah's covenant and their oaths for a small price (3:77). Swearing by Allah on a lie, in order to take money or a right, is a major sin.
وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا ۚ إِنَّ ٱللَّهَ يَعْلَمُ مَا تَفْعَلُونَ ﴿٩١﴾

إِنَّ ٱلَّذِينَ يَشْتَرُونَ بِعَهْدِ ٱللَّهِ وَأَيْمَٰنِهِمْ ثَمَنًۭا قَلِيلًا أُو۟لَٰٓئِكَ لَا خَلَٰقَ لَهُمْ فِى ٱلْءَاخِرَةِ وَلَا يُكَلِّمُهُمُ ٱللَّهُ وَلَا يَنظُرُ إِلَيْهِمْ يَوْمَ ٱلْقِيَٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌۭ ﴿٧٧﴾
