"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»
