Abu Umama reported God’s Messenger as saying, “If anyone appropriates by his oath what rightly belongs to a Muslim, God has made hell necessary for him and deprived him of paradise.” A man asked God’s Messenger whether that applied even if it were a small amount, and he replied, “Even if it were a stick from an <i>arak</i> tree.” Muslim transmitted it.

وَعَنْ أَبِي أُمَامَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنِ اقْتَطَعَ حَقَّ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ فَقَدْ أَوْجَبَ اللَّهُ لَهُ النَّارَ وَحَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ» فَقَالَ لَهُ رَجُلٌ: وَإِنْ كَانَ شَيْئا يسير يَا رَسُولَ اللَّهِ؟ قَالَ: «وَإِنْ كَانَ قَضِيبًا من أَرَاك» . رَوَاهُ مُسلم
