Sahih al-Bukhari, Volume 7, Book 63, Hadith 219 (USC-MSA) ⓘ

Narrated 'Abdullah bin Mas'ud: The Prophet said, "The call (or the Adhan) of Bila should not stop you from taking the Suhur-meals for Bilal calls (or pronounces the Adhan) so that the one who is offering the night prayer should take a rest, and he does not indicate the daybreak or dawn." The narrator, Yazid, described (how dawn breaks) by stretching out his hands and then separating them wide apart.

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 صلى الله عليه وسلم ‏ "‏ 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.‏

Narrated Abu Huraira: Allah's Messenger 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.

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.‏
