Messenger of Allah ﷺ said, The example of a miser and a generous person is like that of two persons wearing iron cloaks from the breast upto the neck When the generous person spends, the iron cloak enlarges and spread over his skin so much so that it covers his fingertips and obliterates his tracks. As for the miser, as soon as he thinks of spending every ring of the iron cloak sticks to its place (against his body) and he tries to expand it, but it does not expand. The Prophet ﷺ pointed with his hand towards his throat.  

قَالَ رَسُولُ اللَّهِ ﷺ مَثَلُ الْبَخِيلِ وَالْمُنْفِقِ كَمَثَلِ رَجُلَيْنِ عَلَيْهِمَا جُبَّتَانِ مِنْ حَدِيدٍ مِنْ لَدُنْ ثَدْيَيْهِمَا إِلَى تَرَاقِيهِمَا فَأَمَّا الْمُنْفِقُ فَلاَ يُنْفِقُ شَيْئًا إِلاَّ مَادَّتْ عَلَى جِلْدِهِ حَتَّى تُجِنَّ بَنَانَهُ وَتَعْفُوَ أَثَرَهُ وَأَمَّا الْبَخِيلُ فَلاَ يُرِيدُ يُنْفِقُ إِلاَّ لَزِمَتْ كُلُّ حَلْقَةٍ مَوْضِعَهَا فَهْوَ يُوسِعُهَا فَلاَ تَتَّسِعُ وَيُشِيرُ بِإِصْبَعِهِ إِلَى حَلْقِهِ  

[Machine] The Messenger of Allah ﷺ said: "The example of the stingy person and the generous person is like that of two people who have two gardens or two pieces of land made of iron. The distance between them is from their chests to their feet. As for the one who spends (in charity), and gives himself regular reminders (to do good), the traces of his good deeds depart from his skin and cover his two sides until they reach his ankles. And as for the stingy person, whenever he spends (in charity) and does something good, it clings to him and does not leave its place. It tightens around him like a ring, and it does not expand."  

قَالَ رَسُولُ اللَّهِ ﷺ «مَثَلُ الْبَخِيلِ وَالْمُتَصَدِّقِ كَمَثَلِ رَجُلَيْنِ عَلَيْهِمَا جُبَّتَانِ أَوْ جَنَّتَانِ مِنْ حَدِيدٍ مِنْ لَدُنْ ثُدِيِّهِمَا إِلَى تَرَاقِيهِمَا فَأَمَّا الْمُنْفِقُ فَكُلَّمَا تَصَدَّقَ وَحَدَّثَ نَفْسَهُ ذَهَبَتْ عَنْ جِلْدِهِ حَتَّى تَعْفُوَ أَثَرَهُ وَتَجُوزَ بَنَانَهُ وَالْبَخِيلُ كُلَّمَا أَنْفَقَ شَيْئًا وَحَدَّثَ بِهِ نَفْسَهُ لَزِمَتْهُ وَعَضَّتْ كُلُّ حَلْقَةٍ مِنْهَا مَكَانَهَا فَهُوَ يُوَسِّعُهَا وَلَا تَتَّسِعُ»  

"مَثَلُ الْبخيلِ والْمُتَصَدِّق كَمَثَلِ رَجُلَين عَليهمَا جُبَّتَانِ منْ حَدِيدٍ مِنْ ثُدِيِّهِما إِلَى تَرَاقِيهمَا، فأَمَّا الْمُنْفِقُ فَلَا يُنْفِقُ إلا سَبغَتْ أَوْ وَقَرَتْ عَلَي جلْدِهِ حَتَّى تُخْفِي بَنَانَهُ، أَوْ تعفوَ أَثَرَهُ، وأَمَّا الْبخِيلُ فَلَا يُريدُ أَنْ يُنْفِقَ شيئًا إِلَّا لَزِقَتْ كُلُّ حَلقَةٍ مكَانَهَا، فَهُو يُوسِّعُهَا فَلَا تَتَّسِعُ".
