Illegality of Swearing Falsely
وَعَنْ أَبِي أُمَامَة إِياس بْن ثعلبةَ اَلْحَارِثِيُّ رَضِيَ اللَّه عَنْهُ أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: "مَنْ اِقْتَطَعَ حَقَّ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ، فَقَدْ أَوْجَبَ اَللَّهُ لَهُ اَلنَّارَ. -وَحَرَّمَ عَلَيْهِ اَلْجَنَّةَ" فَقَالَ لَهُ رَجُلٌ: وَإِنْ كَانَ شَيْئًا يَسِيرًا يَا رَسُولَ اَللَّهِ؟ قَالَ: "وَإِنْ كَانَ قَضِيبًا من أَرَاك" ((رَوَاهُ مُسلم)).
Abu Umamah Iyas bin Tha'labah Al-Harithi (May Allah be pleased with him) said: The Messenger of Allah (ﷺ) said, "He who misappropriates the right of a Muslim by taking a false oath, Allah will condemn him to the fire of Hell and will forbid Jannah for him." A person asked: "O Messenger of Allah, even if it is something insignificant?" He replied, "Yes, even if it is the twig of the Arak tree." [Muslim].
