Bulugh al-Maram 1384
وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا, { عَنْ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-أَنَّهُ نَهَى عَنْ اَلنَّذْرِ وَقَالَ: } مُتَّفَقٌ عَلَيْهِ 1‏ .‏
" إِنَّهُ لَا يَأْتِي بِخَيْرٍ وَإِنَّمَا يُسْتَخْرَجُ بِهِ مِنْ اَلْبَخِيلِ"
Ibn 'Umar (RA):

The Prophet (ﷺ) forbade making vows, and said, "It does not bring good. Indeed, it is only a means by which something is extracted from the miserly." [Agreed upon].
