Sahih al-Bukhari, Hadith 2917 ⓘ

Narrated Abu Huraira: The Prophet said, "The example of a miser and the one who gives in charity, is like the example of two men wearing iron cloaks so tightly that their arms are raised forcibly towards their collar-bones. So, whenever a charitable person wants to give in charity, his cloak spreads over his body so much so that it wipes out his traces, but whenever the miser wants to give in charity, the rings (of the iron cloak) come closer to each other and press over his body, and his hands gets connected to his collarbones. Abu Huraira heard the Prophet saying. "The miser then tries to widen it but in vain."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا ابْنُ طَاوُسٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ مَثَلُ الْبَخِيلِ وَالْمُتَصَدِّقِ مَثَلُ رَجُلَيْنِ عَلَيْهِمَا جُبَّتَانِ مِنْ حَدِيدٍ، قَدِ اضْطَرَّتْ أَيْدِيَهُمَا إِلَى تَرَاقِيهِمَا، فَكُلَّمَا هَمَّ الْمُتَصَدِّقُ بِصَدَقَتِهِ اتَّسَعَتْ عَلَيْهِ حَتَّى تُعَفِّيَ أَثَرَهُ، وَكُلَّمَا هَمَّ الْبَخِيلُ بِالصَّدَقَةِ انْقَبَضَتْ كُلُّ حَلْقَةٍ إِلَى صَاحِبَتِهَا وَتَقَلَّصَتْ عَلَيْهِ وَانْضَمَّتْ يَدَاهُ إِلَى تَرَاقِيهِ ‏"‏‏.‏ فَسَمِعَ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏"‏ فَيَجْتَهِدُ أَنْ يُوَسِّعَهَا فَلاَ تَتَّسِعُ ‏"‏‏.‏
