Sahih Muslim , Book 26, Hadith 7 (In-Book) ⓘ
Abu Heraira reported Allah's Messenger as saying: Do not take vows, for a vow has no effect against Fate; it is only from the miserly that something is extracted.
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ تَنْذُرُوا فَإِنَّ النَّذْرَ لاَ يُغْنِي مِنَ الْقَدَرِ شَيْئًا وَإِنَّمَا يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ " .
