Riyad as-Salihin, 1713

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." <b>[Muslim]</b>.

وعن أبي أُمامة إياس بن ثعلبة الحارثي رضي الله عنه أن رسول الله صلى الله عليه وسلم قال‏:‏ ‏"‏من اقتطع حق امرئ مسلم بيمينه، فقد أوجب الله له النار‏.‏ -وحرم عليه الجنة‏"‏ فقال له رجل‏:‏ وإن كان شيئًا يسيرًا يا رسول الله‏؟‏ قال‏:‏ ‏"‏وإن كان قضيبًا من أراك‏"‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

<b>Guidance from the Hadiths:</b><br> 1) Affirming the gravity of the false oath that a person takes knowingly. It is a major sin that throws the swearer in Hellfire.<br> 2) It is prohibited to take the property of others unjustly, no matter how small it is. Whoever does so incurs the wrath of Allah Almighty and becomes worthy of entering Hellfire.<br> 3) A person should restrain his tongue and be truthful in his speech and oath.<br> 4) The Shariah cares greatly about the rights of people, in terms of their lives, honor, wealth, and the like.
