Hadith 7681- 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 Abi ‘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.’”
