Sahih al-Bukhari 68:48
Narrated Abu Huraira:
Allah's Messenger (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.

وَقَالَ اللَّيْثُ حَدَّثَنِي جَعْفَرُ بْنُ رَبِيعَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ هُرْمُزَ، سَمِعْتُ أَبَا هُرَيْرَةَ، قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " 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.
