1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ عِدَةُ الْمُؤْمِنِ أَخَاهُ نَذْرٌ لا كَفَّارَةَ لَهُ فَمَنْ أَخْلَفَ فَبِخُلْفِ الله بَدَأَ وَلِمَقْتِهِ تَعَرَّضَ وَذَلِكَ قَوْلُهُ يا أَيُّهَا الَّذِينَ آمَنُوا لِمَ تَقُولُونَ ما لا تَفْعَلُونَ كَبُرَ مَقْتاً عِنْدَ الله أَنْ تَقُولُوا ما لا تَفْعَلُونَ.

1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Hisham ibn Salim who has said the following: “I heard abu ‘Abd Allah (a.s.) saying, ‘The promise of a believer to his brother (in belief) is a vow that has no expiation. Whoever violates it has initiated to violate Allah and has subjected himself to His anger as it is said in His words: “Believers, why do you preach what you do not practice? (61:2). It is most hateful in the sight of Allah if you say something and do not practice it.’” (61:3)

2ـ عَلِيٌّ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ شُعَيْبٍ الْعَقَرْقُوفِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) مَنْ كَانَ يُؤْمِنُ بِالله وَالْيَوْمِ الآخِرِ فَلْيَفِ إِذَا وَعَدَ.

2. Ali has narrated from his father from ibn abu ‘Umayr from Shu’ayb al-‘Aqarqufi from abu ‘Abd Allah (a.s.) who has said the following: “The Messenger of Allah has said, ‘Whoever believes in Allah, and in the Day of Judgment, must fulfill his promise.’”
