وَقَدْ مَكَرُواْ مَكْرَهُمْ وَعِندَ اللّهِ مَكْرُهُمْ وَإِن كَانَ مَكْرُهُمْ لِتَزُولَ مِنْهُ الْجِبَالُ
“Even though their cunning was such that the mountains could be vanished”
Imam Sadiq (as) said, “Even though their cunning was such that the mountains could be vanished” means that verily the hearts of men will shake from the “cunning” (deception) of the Bani Abbas regarding the Qaem (as) (Tafseer Ayyashi volume 2 page 234)
Imam Sadiq (as) said, Fear Allah and obey your Imams. Say what (your Imams) say and do not speak about that which they do not speak, since you still live under the government of those whom Allah describes in this verse, “Even though their cunning was such that the mountains could be vanished”.
Fear Allah and (remember) you are in a state of truce with them. Pray with their tribes, attend their funerals, and stay trustworthy, even with them. (Refers to Taqaiyyah with enemies)
