"A vow does not bring anything to the son of Adam that has not been decreed for him. It is just a means of taking wealth from the miserly."

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَأْتِي النَّذْرُ عَلَى ابْنِ آدَمَ شَيْئًا لَمْ يُقَدِّرْهُ عَلَيْهِ وَلَكِنَّهُ شَىْءٌ يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ

The Messenger of Allah ﷺ as saying: A vow does not provide for the son of Adam anything which I did not decree for him, but a vow draws it. A Divine decree is one which I have destined, it is extracted from a miser. He is given what he was not given before. (Using translation from Abū Dāʾūd 3288)

وَقَالَ رَسُولُ اللهِ ﷺ لَا يَأْتِي ابْنَ آدَمَ النَّذْرُ بِشَيْءٍ لَمْ أَكُنْ قَدَّرْتُهُ لَهُ وَلَكِنَّهُ يَلْقِيهِ النَّذْرُ بِمَا قد قَدَّرْتُهُ لَهُ يُسْتَخْرَجُ بِهِ مِنَ الْبَخِيلِ يُؤْتِينِي عَلَيْهِ مَا لَمْ يَكُنْ آتَانِي عَلَيْهِ مِنْ قَبْلُ

[Machine] "On the authority of the Prophet ﷺ , Allah (God) said: 'No vow made by the son of Adam (human) comes to me in which I do not decree for him what I have prescribed, but it is a way of extracting from the miser (stingy person) what I have not decreed for him to give me.'"

عَنِ النَّبِيِّ ﷺ قَالَ قَالَ اللهُ ﷻ لَا يَأْتِي النَّذْرُ عَلَى ابْنِ آدَمَ بِشَيْءٍ لَمْ أُقَدِّرْهُ عَلَيْهِ وَلَكِنَّهُ شَيْءٌ أَسْتَخْرِجُ بِهِ مِنَ الْبَخِيلِ يُؤْتِينِي عَلَيْهِ مَا لَا يُؤْتِينِي عَلَى الْبُخْلِ

"A vow does not bring anything to the son of Adam that has not been decreed for him. It is just a means of taking wealth from the miserly." (Using translation from Nasāʾī 3804)

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَأْتِي النَّذْرُ عَلَى ابْنِ آدَمَ شَيْئًا لَمْ يُقَدَّرْ عَلَيْهِ وَلَكِنَّهُ شَيْءٌ اسْتُخْرِجَ بِهِ مِنَ الْبَخِيلِ

اللَّهُ عَلَيه وَسَلَّم النذر لا يقرب شيئا لم يكن الله قدره وَلكن النذر يستخرج به من البخيل ما لم يكن يريد أن يخرجه
