حَدَّثَنَا يَزِيدُ أَخْبَرَنَا نَافِعٌ عَنِ ابْنِ أَبِي مُلَيْكَةَ قَالَ كَتَبَ إِلَيَّ ابْنُ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْيَمِينُ عَلَى الْمُدَّعَى عَلَيْهِ وَلَوْ أَنَّ النَّاسَ أُعْطُوا بِدَعْوَاهُمْ لَادَّعَى نَاسٌ أَمْوَالًا كَثِيرَةً وَدِمَاءًٍ
مسند امام احمد بن حنبل · Hadith 3292
It was narrated that Ibn Abi Mulaikah said: Ibn 'Abbas (RA) wrote to me (saying) that the Messenger of Allah (PBUH) said: "The one against whom a claim is made should swear an oath. If people were to be given on the basis of what they claim, people would claim a lot of wealth and lives".
