"Whoever makes a vow and does not state it specifically, the expiation (for such a vow) is the expiation for breaking an oath. Whoever makes a vow and is not able to fulfill it, the expiation for that is the expiation for breaking an oath. Whoever makes a vow and is able to fulfill it, let him do so."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ نَذَرَ نَذْرًا وَلَمْ يُسَمِّهِ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا لَمْ يُطِقْهُ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا أَطَاقَهُ فَلْيَفِ بِهِ  

[Machine] "Narrated by the Messenger of Allah ﷺ, 'Whoever makes a vow but does not specify it, then its expiation is like the expiation of an oath. And whoever makes a vow in disobedience to Allah, then its expiation is like the expiation of an oath. And whoever makes a vow that they cannot afford, then its expiation is the expiation of an oath. And whoever makes a vow that they can afford, then let them fulfill it.'"  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «مَنْ نَذَرَ نَذْرًا لَمْ يُسَمِّهِ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا فِي مَعْصِيَةِ اللهِ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا لَا يُطِيقُهُ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا يُطِيقُهُ فَلْيَفِ»  

"مَنْ نَذَرَ نَذْرًا (وَ) (*) لَمْ يُسَمِّهِ فَكَفارَتُهُ كفَّارَةُ يَمينٍ، وَمَنْ نَذَرَ (نَذْرًا) (* *) فِي مَعْصِيةٍ فَكَفَّارتُه كفَّارَةُ يَمِينٍ، وَمَنْ نَذَرَ نَذْرًا لا يُطِيقهُ فَكَفَّارتُه كفَّارَةُ يَمِينٍ".
