Hadith 7514- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ يَحْيَى بْنِ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ أَبِي سَلامٍ الْمُتَعَبِّدِ أَنَّهُ سَمِعَ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) يَقُولُ لِسَدِيرٍ يَا سَدِيرُ مَنْ حَلَفَ بِاللهِ كَاذِباً كَفَرَ وَمَنْ حَلَفَ بِاللهِ صَادِقاً أَثِمَ إِنَّ اللهَ عَزَّ وَجَلَّ يَقُولُ وَلا تَجْعَلُوا اللهَ عُرْضَةً لأيْمانِكُمْ.
4. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Yahya ibn Ibrahim from his father from abu Salam al-Salam al-Muta‘abbid who has said the following: “I once heard abu ‘Abd Allah (a.s.), saying to Sadir, ‘O Sadir, one who swears by Allah, most Majestic, most Glorious, falsely as well as one who swears by Allah truthfully has sinned; Allah, most Majestic, most Glorious, says, ‘Do not swear by Allah, unless you are obligated.’ (2:224)”
