It was narrated from Abu Umamah that :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."
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنَا الْعَلاَءُ، عَنْ مَعْبَدِ بْنِ كَعْبٍ، عَنْ أَخِيهِ عَبْدِ اللَّهِ بْنِ كَعْبٍ، عَنْ أَبِي أُمَامَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنِ اقْتَطَعَ حَقَّ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ فَقَدْ أَوْجَبَ اللَّهُ لَهُ النَّارَ وَحَرَّمَ عَلَيْهِ الْجَنَّةَ " . فَقَالَ لَهُ رَجُلٌ وَإِنْ كَانَ شَيْئًا يَسِيرًا يَا رَسُولَ اللَّهِ قَالَ " وَإِنْ كَانَ قَضِيبًا مِنْ أَرَاكٍ " .
