It was narrated that Ibn 'Umar said: "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.'"
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " النَّذْرُ لاَ يُقَدِّمُ شَيْئًا وَلاَ يُؤَخِّرُهُ إِنَّمَا هُوَ شَىْءٌ يُسْتَخْرَجُ بِهِ مِنَ الشَّحِيحِ " .
