"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.'" (Using translation from Nasāʾī 3803)  

قَالَ رَسُولُ اللهِ ﷺ «النَّذْرُ لَا يُقَدِّمُ شَيْئًا وَلَا يُؤَخِّرُهُ إِنَّمَا هُوَ شَيْءٌ 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." (Using translation from Nasāʾī 3804)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَأْتِي النَّذْرُ عَلَى ابْنِ آدَمَ شَيْئًا لَمْ يُقَدَّرْ عَلَيْهِ وَلَكِنَّهُ شَيْءٌ اسْتُخْرِجَ بِهِ مِنَ الْبَخِيلِ
