Hadith 7481- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ أَبِي أَيُّوبَ الْخَزَّازِ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) يَقُولُ لا تَحْلِفُوا بِاللهِ صَادِقِينَ وَلا كَاذِبِينَ فَإِنَّهُ عَزَّ وَجَلَّ يَقُولُ وَلا تَجْعَلُوا اللهَ عُرْضَةً لأيْمانِكُمْ.
