Sahih Muslim , Book 26, Hadith 4 (In-Book) ⓘ
Ibn Umar reported Allah's Apostle as saying: The vow neither hastens anything nor defers anything, but is the means whereby (something) is extracted from the miserly person.
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا يَزِيدُ بْنُ أَبِي حَكِيمٍ، عَنْ سُفْيَانَ، عَنْ عَبْدِ اللَّهِ بْنِ، دِينَارٍ عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ " النَّذْرُ لاَ يُقَدِّمُ شَيْئًا وَلاَ يُؤَخِّرُهُ وَإِنَّمَا يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ " .
