“Whoever demands his rights let him do so in a decent manner as much as he can.” (Using translation from Ibn Mājah 2421)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ طَلَبَ حَقًّا فَلْيَطْلُبْهُ فِي عَفَافٍ وَافٍ أَوْ غَيْرَ وَافٍ»  

(the slave of Ibn ʿAbbas) Messenger of Allah ﷺ said to Muʿadh when he sent him to Yemen, "You will go to the people of the Scripture. So, when you reach there, invite them to testify that none has the right to be worshipped but Allah, and that Muhammad is His Apostle. And if they obey you in that, tell them that Allah has enjoined on them five prayers in each day and night. And if they obey you in that tell them that Allah has made it obligatory on them to pay the Zakat which will be taken from the rich among them and given to the poor among them. If they obey you in that, then avoid taking the best of their possessions, and be afraid of the curse of an oppressed person because there is no screen between his invocation and Allah." (Using translation from Bukhārī 1496)  

لَمَّا بَعَثَ رَسُولُ اللَّهِ ﷺ مُعَاذًا إِلَى الْيَمَنِ فَقَالَ «إِنَّكَ سَتَأْتِي قَوْمًا أَهْلَ كِتَابٍ فَإِذَا جِئْتَهُمْ فَادْعُهُمْ إِلَى أَنْ يَشْهَدُوا أَنَّ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ فَإِذَا أَطَاعُوا لَكَ بِذَلِكَ فَأَخْبِرْهُمْ أَنَّ اللَّهَ فَرَضَ عَلَيْهِمْ صَلَوَاتٍ خَمْسًا فِي كُلِّ يَوْمٍ وَلَيْلَةٍ فَإِنْ هُمْ أَطَاعُوا لَكَ بِذَلِكَ فَأَخْبِرْهُمْ أَنَّ اللَّهَ جَلَّ وَعَلَا فَرَضَ عَلَيْهِمْ صَدَقَةً تُؤْخَذُ مِنْ أَغْنِيَائِهِمْ فَتُرَدُّ عَلَى فُقَرَائِهِمْ فَإِنْ أَطَاعُوا لَكَ بِذَلِكَ فَإِيَّاكَ وَكَرَائِمَ أَمْوَالِهِمْ وَاتَّقِ دَعْوَةَ الْمَظْلُومِ فَإِنَّهُ لَيْسَ بَيْنَ اللَّهِ وَبَيْنَهُ حِجَابٌ»  

[Machine] "That two women who were staying in the house together, other than them, went out. One of them came back with a stab wound on her stomach, and blood was coming out from the back of her hand. She said her companion stabbed her, while the other denied it. So, they sent a message to Ibn Abbas about the incident, and they informed him of the matter. He said, 'Do not give anything unless there is evidence, for the Messenger of Allah ﷺ said, "If people were given what they claimed, people would falsely claim the wealth and blood of others. But the burden of proof is upon the claimant, so make her swear an oath and recite Surah Al-Imran: 'Indeed, those who exchange the covenant of Allah and their [own] oaths for a small price...'" So, I did that, and she confessed.'"  

أَنَّ امْرَأَتَيْنِ كَانَتَا تَخْرُزَانِ لَيْسَ مَعَهُمَا فِي الْبَيْتِ غَيْرَهُمَا فَخَرَجَتْ إِحْدَاهُمَا قَدْ طُعِنَ فِي بَطْنِ كَفِّهَا بِإِشْفَى خَرَجَ مِنْ ظَهْرِ كَفِّهَا تَقُولُ طَعَنَتْهَا صَاحِبَتُهَا وَتُنْكِرُ الْأُخْرَى فَأَرْسَلَتْ إِلَى ابْنِ عَبَّاسٍ فِيهِمَا فَأَخْبَرَتْهُ الْخَبَرَ فَقَالَ لَا تُعْطِي شَيْئًا إِلَّا بِالْبَيِّنَةِ فَإِنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَوْ يُعْطَى النَّاسُ بِدَعْوَاهُمْ لَادَّعَى رِجَالٌ أَمْوَالَ رِجَالٍ وَدِمَاءَهُمْ وَلَكِنَّ الْيَمِينَ عَلَى الْمُدَّعَى عَلَيْهِ فَادْعُهَا فَاقْرَأْ عَلَيْهَا الْقُرْآنَ وَاقْرَأْ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلًا} فَفَعَلْتُ فَاعْتَرَفَتْ»  

“If the people were given what they claimed, some would have claimed the lives and property of men. But the one the claim is made against is obliged to swear an oath.” (Using translation from Ibn Mājah 2321)  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «لَوْ يُعْطَى النَّاسُ بِدَعْوَاهُمْ لَادَّعَى النَّاسُ دِمَاءَ رِجَالٍ وَأَمْوَالَهُمْ وَلَكِنَّ الْيَمِينَ عَلَى الْمُدَّعَى عَلَيْهِ»  

[Machine] The Prophet ﷺ said, "Whoever swears an oath on a matter in which he is lying, in order to unlawfully take someone's property, then he has met Allah while He is angry with him." The confirmation of this was revealed in the Qur'an in the verse {Indeed, those who exchange the covenant of Allah}. Al-Ash'ath ibn Qays passed by them while they were discussing this hadith in the mosque and he asked, "What does Ibn Umm 'Abd say?" They informed him, so he said, "He spoke the truth, indeed this verse was revealed concerning me and my companion in a well that I claimed and none of us had any proof, so he swore an oath on it. The Prophet ﷺ mentioned this at that time."  

قَالَ النَّبِيُّ ﷺ «مَنْ حَلَفَ عَلَى يَمِينٍ هُوَ فِيهَا فَاجِرٌ لِيَقْتَطِعَ بِهَا مَالًا لَقِيَ اللَّهَ وَهُوَ عَلَيْهِ غَضْبَانُ» وَنَزَلَ تَصْدِيقُ ذَلِكَ فِي كِتَابِ اللَّهِ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللَّهِ} الْآيَةَ فَمَرَّ الْأَشْعَثُ بْنُ قَيْسٍ وَهُمْ يَتَحَدَّثُونَ بِهَذَا الْحَدِيثِ فِي الْمَسْجِدِ فَقَالَ مَا يَقُولُ ابْنُ أُمِّ عَبْدٍ؟ فَأَخْبَرُوهُ فَقَالَ صَدَقَ إِنَّمَا نَزَلَتْ هَذِهِ الْآيَةُ فِيَّ وَفِي صَاحِبِي فِي بِئْرٍ ادَّعَيْتُهَا وَلَمْ يَكُنْ لِأَحَدٍ مِنَّا بَيِّنَةٌ فَحَلَفَ عَلَيْهَا فَذَكَرَ نَبِيُّ اللَّهِ ﷺ هَذَا عِنْدَ ذَلِكَ
