4. An Oath is not Valid except by Allah, One who does not Agree with Allah is not of Allah
Back to book1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مَنْصُورِ بْنِ يُونُسَ عَنْ أَبِي حَمْزَةَ عَنْ عَلِيِّ بْنِ الْحُسَيْنِ (عَلَيْهِما السَّلام) قَالَ قَالَ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) لا تَحْلِفُوا إِلا بِاللهِ وَمَنْ حَلَفَ بِاللهِ فَلْيَصْدُقْ وَمَنْ حُلِفَ لَهُ بِاللهِ فَلْيَرْضَ وَمَنْ حُلِفَ لَهُ بِاللهِ فَلَمْ يَرْضَ فَلَيْسَ مِنَ اللهِ عَزَّ وَجَلَّ.
1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Mansur ibn Yunus from abu Hamzah who has narrated the following: “Ali ibn al-Husayn, ‘Alayhim al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘Do not swear except by Allah and one who swears by Allah must be considered truthful. One must agree with an oath by Allah. If one does not agree with an oath by Allah, is not of Allah, most Majestic, most Glorious.’”

2- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ مَنْ حَلَفَ بِاللهِ فَلْيَصْدُقْ وَمَنْ لَمْ يَصْدُقْ فَلَيْسَ مِنَ اللهِ وَمَنْ حُلِفَ لَهُ بِاللهِ عَزَّ وَجَلَّ فَلْيَرْضَ وَمَنْ لَمْ يَرْضَ فَلَيْسَ مِنَ اللهِ عَزَّ وَجَلَّ.
2. A number of our people have narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from abu Ayyub al-Khazzaz who has narrated the following: “Abu ‘Abd Allah, Alayhi al-Salam, has said, ‘If one swears by Allah it must be considered true, if one does not believe he is not of Allah. One must agree with an oath by Allah, if he does do so he is not of Allah, most Majestic, most Glorious.’”
