Safwan reported from a number of Companions of the Messenger of Allah ﷺ on the authority of their fathers who were relatives of each other. The Messenger of Allah ﷺ said: Beware, if anyone wrongs a contracting man, or diminishes his right, or forces him to work beyond his capacity, or takes from him anything without his consent, I shall plead for him on the Day of Judgment.  

أَخْبَرَهُ عَنْ عِدَّةٍ مِنْ أَبْنَاءِ أَصْحَابِ رَسُولِ اللَّهِ ﷺ عَنْ آبَائِهِمْ دِنْيَةً عَنْ رَسُولِ اللَّهِ ﷺ قَالَ أَلاَ مَنْ ظَلَمَ مُعَاهِدًا أَوِ انْتَقَصَهُ أَوْ كَلَّفَهُ فَوْقَ طَاقَتِهِ أَوْ أَخَذَ مِنْهُ شَيْئًا بِغَيْرِ طِيبِ نَفْسٍ فَأَنَا حَجِيجُهُ يَوْمَ الْقِيَامَةِ  

[Machine] He informed him about thirty of the sons of the companions of the Messenger of Allah ﷺ, who narrated from their fathers, who narrated from the Messenger of Allah ﷺ that he said, "Verily, whoever wrongs a person with a covenant and diminishes his rights or burdens him with a task beyond his ability or takes something from him without his consent, then I am his adversary on the Day of Resurrection. And Allah's Messenger ﷺ pointed with his index finger towards his chest and said, "Verily, whoever kills a person who has a covenant, then he will not smell the fragrance of Paradise, even though its fragrance can be perceived from a distance of seventy years of travel."  

أَخْبَرَهُ عَنْ ثَلَاثِينَ مِنْ أَبْنَاءِ أَصْحَابِ رَسُولِ اللهِ ﷺ عَنْ آبَائِهِمْ دِنْيَةً عَنْ رَسُولِ اللهِ ﷺ قَالَ أَلَا مَنْ ظَلَمَ مُعَاهَدًا وَانْتَقَصَهُ وَكَلَّفَهُ فَوْقَ طَاقَتِهِ أَوْ أَخَذَ مِنْهُ شَيْئًا بِغَيْرِ طِيبِ نَفْسٍ مِنْهُ فَأَنَا حَجِيجُهُ يَوْمَ الْقِيَامَةِ وَأَشَارَ رَسُولُ اللهِ ﷺ بِأُصْبُعِهِ إِلَى صَدْرِهِ أَلَا وَمَنْ قَتَلَ مُعَاهَدًا لَهُ ذِمَّةُ اللهِ وَذِمَّةُ رَسُولِهِ حَرَّمَ اللهُ عَلَيْهِ رِيحَ الْجَنَّةِ وَإِنَّ رِيحَهَا لَتُوجَدُ مِنْ مَسِيرَةِ سَبْعِينَ خَرِيفًا  

"مَنْ ظَلَمَ مُعَاهَدًا مُقِرًّا بِذِمَّتِهِ، مُؤَدِّيًا لِجِزْيَتِهِ كُنتُ خَصْمَهُ يَوْمَ الْقِيَامَةِ".
