سورة القلم

Ibn Abbas (may Allah have mercy on him): فَأَقْبَلَ بَعْضُهُمْ عَلَی بَعْضٍ یَتَلَاوَمُونَ [Then some of them advanced against others, blaming each other]; they were blaming one another over that evil decision they had made.

Imam Baqir (peace be upon him): Imam Baqir (peace be upon him) was asked about this verse: "Stop them, for they must be questioned!" (Saffat/24), and he said: "They will stand and be asked: what is the matter with you that you do not help one another in the Hereafter, just as you helped one another in the world against Ali (peace be upon him)?" Allah says: but on that day they are submissive [before Allah's power]. فَأَقْبَلَ بَعْضُهُمْ عَلَی بَعْضٍ یَتَلَاوَمُونَ [Then some of them advanced against others, blaming each other].

Imam Ali (peace be upon him): O Allah! I seek Your forgiveness for every sin that causes blackening of faces on the day when the faces of Your friends [on that day] become white and the faces of Your enemies become black; when they turned to one another blaming each other. Then it was said to them: do not quarrel in My presence; I had already warned you beforehand [and completed the argument against you]!
