The Messenger of Allah ﷺ as saying: If anyone vows to obey Allah, let him obey Him, but if anyone vows to disobey Him, let him not disobey Him. (Using translation from Abū Dāʾūd 3289)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ نَذَرَ أَنْ يُطِيعَ اللهَ فَلْيُطِعْهُ وَمَنْ نَذَرَ أَنْ يَعْصِيَ اللهَ فَلَا يَعْصِهِ»  

[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever vows to obey Allah, let him obey Him. And whoever vows to disobey Allah, let him not disobey Him." Abu Abdur-Rahman Talhah ibn Abdil-Malik said, "He is a trustworthy narrator."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ نَذَرَ أَنْ يُطِيعَ اللهَ فَلْيُطِعْهُ وَمَنْ نَذَرَ أَنْ يَعْصِيَ اللهَ فَلَا يَعْصِهِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ طَلْحَةَ بْنِ عَبْدِ الْمَلِكِ ثِقَةٌ ثِقَةٌ ثِقَةٌ
