Sahih al-Bukhari 6609
Narrated Abu Huraira:
The Prophet (ﷺ) said (that Allah said), "Vowing does not bring to the son of Adam anything I have not 
already written in his fate, but vowing is imposed on him by way of fore ordainment. Through vowing 
I make a miser spend of his wealth."
حَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ لاَ يَأْتِي ابْنَ آدَمَ النَّذْرُ بِشَىْءٍ لَمْ يَكُنْ قَدْ قَدَّرْتُهُ، وَلَكِنْ يُلْقِيهِ الْقَدَرُ وَقَدْ قَدَّرْتُهُ لَهُ، أَسْتَخْرِجُ بِهِ مِنَ الْبَخِيلِ ‏"‏‏.‏
