Sahih al-Bukhari 6609Book 82, Hadith 15
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 ".
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."
