The Prophet ﷺ said: Delay in payment on the part of one who possesses means makes it lawful to dishonour and punish him. Ibn al-Mubarak said that "dishonour" means that he may be spoken to roughly and "punish" means he may be imprisoned for it.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ لَىُّ الْوَاجِدِ يُحِلُّ عِرْضَهُ وَعُقُوبَتَهُ قَالَ ابْنُ الْمُبَارَكِ يُحِلُّ عِرْضَهُ يُغَلَّظُ لَهُ وَعُقُوبَتَهُ يُحْبَسُ لَهُ  

I brought my debtor to the Holy Prophet ﷺ. He said to me: Stick to him. He again said to me: O brother of Banu Tamim, what do you want to do with your prisoner.  

أَتَيْتُ النَّبِيَّ ﷺ بِغَرِيمٍ لِي فَقَالَ لِي الْزَمْهُ ثُمَّ قَالَ لِي يَا أَخَا بَنِي تَمِيمٍ مَا تُرِيدُ أَنْ تَفْعَلَ بِأَسِيرِكَ  

Bahz bin Hakim, on his father's authority, said that his grandfather told that the Prophet ﷺ imprisoned a man on suspicion.  

أَنَّ النَّبِيَّ ﷺ حَبَسَ رَجُلاً فِي تُهْمَةٍ  

(Ibn Qudamah's version has: His grandfather's brother or uncle reported:) - the narrator Mu'ammal said: - He (his grandfather Mu'awiyah) got up before the Holy Prophet ﷺ who was giving sermon: and he said: Why have your companions arrested my neighbours? He turned away from him twice. He (his grandfather Mu'awiyah) then mentioned something. The Holy Prophet ﷺ then said: Let his neighbours go. (Mu'ammal did not mention the words "He was giving sermon.")  

وَقَالَ مُؤَمَّلٌ إِنَّهُ قَامَ إِلَى النَّبِيِّ ﷺ وَهُوَ يَخْطُبُ فَقَالَ جِيرَانِي بِمَا أَخَذُوا فَأَعْرَضَ عَنْهُ مَرَّتَيْنِ ثُمَّ ذَكَرَ شَيْئًا فَقَالَ النَّبِيُّ ﷺ خَلُّوا لَهُ عَنْ جِيرَانِهِ لَمْ يَذْكُرْ مُؤَمَّلٌ وَهُوَ يَخْطُبُ
