وَ فِي رِوَايَةِ أَبِي خَدِيجَةَ سَالِمِ بْنِ مُكْرَمٍ اَلْجَمَّالِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "اَلْكَذِبُ عَلَى اَللَّهِ وَ عَلَى رَسُولِهِ وَ عَلَى اَلْأَوْصِيَاءِ عَلَيْهِمُ اَلسَّلاَمُ مِنَ اَلْكَبَائِرِ".
In the narration of Abu Khadijah Salim ibn Mukarram al-Jammal from Abu Abdillah (a.s), he said: "Lying against Allah (swt), His Messenger (saws), and the successors (a.s) (peace be upon them) is among the major sins."
