"The Messenger of Allah said: 'A vow does not bring anything forward or put it back; it is just a means of taking wealth from the miserly.'"  

قَالَ رَسُولُ اللَّهِ ﷺ النَّذْرُ لاَ يُقَدِّمُ شَيْئًا وَلاَ يُؤَخِّرُهُ إِنَّمَا هُوَ شَىْءٌ يُسْتَخْرَجُ بِهِ مِنَ الشَّحِيحِ  

"A vow does not bring anything to the son of Adam that has not been decreed for him. It is just a means of taking wealth from the miserly."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَأْتِي النَّذْرُ عَلَى ابْنِ آدَمَ شَيْئًا لَمْ يُقَدِّرْهُ عَلَيْهِ وَلَكِنَّهُ شَىْءٌ يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ
