[Machine] Whoever makes a vow but does not specify it, the expiation is the expiation of an oath. And whoever makes a vow in disobedience to Allah, the expiation is the expiation of an oath. And whoever makes a vow but cannot fulfill it, the expiation is the expiation of an oath. And whoever makes a vow and is able to fulfill it, then let him do so. And thus it was narrated from Talhah bin Yahya, from him, from Abdullah bin Sa'id bin Abi Hind, from Bukair, and from him, from Dahhak bin Uthman, from Abdullah bin Sa'id bin Abi Hind. And it was narrated by Waki' bin Al-Jarrah, from Abdullah bin Sa'id, traced back to Ibn Abbas. And it was narrated from another weak source, from Ibn Abbas.
اللهِ ﷺ مَنْ نَذَرَ نَذْرًا لَمْ يُسَمِّهِ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا فِي مَعْصِيَةِ اللهِ ﷻِّ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا لَمْ يُطِقْهُ فَكَفَّارَتُهُ كَفَّارَةُ يَمِينٍ وَمَنْ نَذَرَ نَذْرًا فَأَطَاقَهُ فَلْيَفِ بِهِ وَهَكَذَا رُوِيَ عَنْ طَلْحَةَ بْنِ يَحْيَى تَارَةً عَنْهُ عَنْ عَبْدِ اللهِ بْنِ سَعِيدِ بْنِ أَبِي هِنْدَ عَنْ بُكَيْرٍ وَتَارَةً عَنْهُ عَنِ الضَّحَّاكِ بْنِ عُثْمَانَ عَنْ عَبْدِ اللهِ بْنِ سَعِيدِ بْنِ أَبِي هِنْدَ وَرَوَاهُ وَكِيعُ بْنُ الْجَرَّاحِ عَنْ عَبْدِ اللهِ بْنِ سَعِيدٍ مَوْقُوفًا عَلَى ابْنِ عَبَّاسٍ ؓ وَرُوِيَ مِنْ وَجْهٍ آخَرَ ضَعِيفٍ عَنِ ابْنِ عَبَّاسٍ
