The Messenger of Allah [SAW] said: "Whoever seizes the wealth of a Muslim unlawfully by means of his (false) oath, Allah makes the Fire required for him, Paradise unlawful for him." A man said to him: "O Messenger of Allah, even if it is something small?" He said: "Even if it is a twig of an Arak tree." (Using translation from Nasāʾī 5419)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنِ اقْتَطَعَ مَالَ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ حَرَّمَ اللهُ عَلَيْهِ الْجَنَّةَ وَأَوْجَبَ لَهُ النَّارَ» قَالُوا وَإِنْ كَانَ شَيْئًا يَسِيرًا يَا رَسُولَ اللهِ؟ قَالَ «وَإِنْ كَانَ قَضِيبًا مِنْ أَرَاكٍ» قَالَهَا ثَلَاثَ مَرَّاتٍ
