Bulugh al-Maram, Book 14, Hadith 1425 (English) ⓘ

Narrated Abu Umamah al-Harithi (RA): Allah's Messenger said. "If anyone seized - by his oath - what rightly belongs to a Muslim, Allah has made the Hell-fire compulsory for him and forbidden for him the Paradise." A man asked, "O Allah's Messenger, even if it were something insignificant?" He replied, "Even if it were a stick from an Arak tree." [Reported by Muslim].

وَعَنْ أَبِي أُمَامَةَ اَلْحَارِثِيُّ ‏- رضى الله عنه ‏- أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-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 قَضِيبٌ مِنْ أَرَاكٍ" } رَوَاهُ مُسْلِم ٌ 1‏.‏ ‏1 ‏- صحيح.‏ رواه مسلم ( 137 )‏، وعنده: "وإن قضيبا".‏
