وَ رُوِيَ عَنِ اَلْمُفَضَّلِ بْنِ عُمَرَ اَلْجُعْفِيِّ قَالَ سَمِعْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يَقُولُ: "فِي قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ: فَلاٰ أُقْسِمُ بِمَوٰاقِعِ اَلنُّجُومِ وَ إِنَّهُ لَقَسَمٌ لَوْ تَعْلَمُونَ عَظِيمٌ يَعْنِي بِهِ اَلْيَمِينَ بِالْبَرَاءَةِ مِنَ اَلْأَئِمَّةِ عَلَيْهِمُ اَلسَّلاَمُ يَحْلِفُ بِهَا اَلرَّجُلُ يَقُولُ إِنَّ ذَلِكَ عِنْدَ اَللَّهِ عَظِيمٌ".
Al-Mufaddal ibn Umar al-Ju'fi narrated that he heard Abu Abdillah (a.s) say regarding the words of Allah (swt), the Almighty and Glorious: "But no! I swear by the setting of the stars. And indeed, it is a mighty oath-if you only knew" (Surah Al-Waqi'ah 56:75-76). Imam (a.s) said: "It refers to the oath of disassociation from the Imams (peace be upon them), where a man swears by it. Verily, such an oath is considered great in the sight of Allah (swt)."
