Hellfire is the punishments for the one who cheats on the rights of others through false testimony

The Messenger of Allah ﷺ said: “I am only a human being, and you bring your disputes to me. Perhaps one of you is more eloquent in presenting his argument than another, so I judge according to what I hear. So whoever I have ruled in his favor for something that is actually his brother’s right should not take it, for I would only be granting him a piece of the Fire.”

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «إِنَّمَا أَنَا بَشَرٌ، وَإِنَّكُمْ تَخْتَصِمُونَ إِلَىَّ. وَلَعَلَّ بَعْضَكُمْ أَنْ يَكُونَ أَلْحَنَ بِحُجَّتِهِ مِنْ بَعْضٍ، فَأَقْضِي نَحْوَ مَا أَسْمَعُ. فَمَنْ قَضَيْتُ لَهُ بِحَقِّ أَخِيهِ شَيْئًا فَلاَ يَأْخُذْهُ، فَإِنَّمَا أَقْطَعُ لَهُ قِطْعَةً مِنَ النَّارِ».
