[Machine] The Messenger of Allah ﷺ ruled that the burden of proof is on the plaintiff, even if people were given based on their claims. People will make claims regarding others' lives and wealth, so make your claim and recite upon it: "Indeed, those who exchange the covenant of Allah and their [own] oaths for a small price will have no share in the hereafter, and Allah will not speak to them or look at them on the Day of Resurrection, nor will He purify them; and they will have a painful punishment." [Surah Al-Imran 3:77]. It is said that Ibn Abbas acknowledged this, and he explained its meaning.
رَسُولَ اللهِ ﷺ قَضَى أَنَّ الْيَمِينَ عَلَى الْمُدَّعَى عَلَيْهِ وَلَوْ أَنَّ النَّاسَ أُعْطُوا بِدَعْوَاهُمُ ادَّعَى نَاسٌ دِمَاءَ أُنَاسٍ وَأَمْوَالَهُمْ فَادْعُهَا وَاقْرَأْ عَلَيْهَا {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلًا أُولَئِكَ لَا خَلَاقَ لَهُمْ فِي الْآخِرَةِ وَلَا يُكَلِّمُهُمُ اللهُ وَلَا يَنْظُرُ إِلَيْهِمْ يَوْمَ الْقِيَامَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ} [آل عمران 77] قَالَ فَاعْتَرَفَتْ فَبَلَغَ ذَلِكَ ابْنَ عَبَّاسٍ فَسَّرَهُ
