Narrated Abu Huraira:

Allah's Apostle 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 pointed with his hand towards his throat.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ سُلَيْمَانَ التَّيْمِيِّ، عَنْ أَبِي عُثْمَانَ، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ ﷺ
" لاَ يَمْنَعَنَّ أَحَدًا مِنْكُمْ نِدَاءُ بِلاَلٍ ـ أَوْ قَالَ أَذَانُهُ ـ مِنْ سَحُورِهِ، فَإِنَّمَا يُنَادِي أَوْ قَالَ يُؤَذِّنُ لِيَرْجِعَ قَائِمُكُمْ ". وَلَيْسَ أَنْ يَقُولَ كَأَنَّهُ يَعْنِي الصُّبْحَ أَوِ الْفَجْرَ، وَأَظْهَرَ يَزِيدُ يَدَيْهِ ثُمَّ مَدَّ إِحْدَاهُمَا مِنَ الأُخْرَى.
