حَدَّثَنَا أَبُو كَامِلٍ حَدَّثَنَا نَافِعٌ عَنِ ابْنِ أَبِي مُلَيْكَةَ قَالَ كَتَبْتُ إِلَى ابْنِ عَبَّاسٍ فَكَتَبَ إِلَيَّ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ الْيَمِينَ عَلَى الْمُدَّعَى عَلَيْهِ وَلَوْ أُعْطِيَ النَّاسُ بِدَعْوَاهُمْ لَادَّعَى أُنَاسٌ أَمْوَالَ النَّاسِ وَدِمَاءَهُمْ
مسند امام احمد بن حنبل · Hadith 3427
It was narrated that Ibn Abi Mulaikah said: I wrote to Ibn 'Abbas and he wrote to me saying: The Messenger of Allah (PBUH) said: "The one against whom a claim is made should swear an oath. If people were given in accordance with their claims, some people would make claims against others' wealth and lives."
