عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَوْ يُعْطَى النَّاسُ بِدَعْوَاهُمْ لَادَّعَى نَاسٌ دِمَاءَ رِجَالٍ وَأَمْوَالَهُمْ وَلَكِنَّ الْيَمِينَ عَلَى الْمُدَّعَى عَلَيْهِ» . رَوَاهُ مُسْلِمٌ وَفِي «شَرْحِهِ لِلنَّوَوِيِّ» أَنَّهُ قَالَ: وَجَاءَ فِي رِوَايَةِ «الْبَيْهَقِيِّ» بِإِسْنَادٍ حَسَنٍ أَوْ صَحِيحٍ زِيَادَةٌ عَنِ ابْنِ عَبَّاسٍ مَرْفُوعًا: «لَكِنَّ الْبَيِّنَةَ على المدَّعي واليمينَ على مَنْ أنكر»

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 arak tree.” Muslim transmitted it.
