The Book of Oaths and Vows
A Vow Is A Means Of Taking Wealth From The Miserly
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ، عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لاَ تَنْذِرُوا فَإِنَّ النَّذْرَ لاَ يُغْنِي مِنَ الْقَدَرِ شَيْئًا وَإِنَّمَا يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ .
It was narrated from Abu Hurairah that the Prophet (ﷺ) said: "Do not make vows, for a vow does not have any impact on the Qadar. Rather it is just a means of taking wealth from the miserly."
