‘What they feared’ means from whom they were afraid—like killing and calamities.
‘What they feared’ means from whom they were afraid—like killing and calamities. If it had meant the overpowering of Firon by Moosa then what was the purpose of singular pronoun, it would have been plural. That is why Moosa and Firon are mentioned as examples.
It means in the way Firon did much injustice on Moosa and his companions for a long period, at last we gave victory to Moosa and destroyed them all, in the same way, different kinds of injustices, will be committed by the Firon of this nation on the Ahlul Bayt (a.s.) but in the end We would bring them in this world again along with their enemies, so that they take revenge from them. Indeed, Ali (a.s.) has pointed towards this in some of his sermons. He says: O people!
The first person to revolted against Allah on the earth was Unaq, the daughter of Adam. The Almighty Allah had given her twenty fingers. Each finger had two long nails like sickles, that are used to cut crops. When she sat she used to cover sixty yards of land. When she revolted against Allah, became an unbeliever and committed injustice on the people, Allah raised a lion as big as an elephant, a Wolf as big a camel and a vulture as big as a donkey to kill her.
These animals were so huge since the very beginning. The Almighty Allah made those animals attack her till she was killed. Allah killed Firon and Haman that is the first and the second (caliph) and buried alive Qaroon, it means the third one.
After this Ali (a.s.) in this manner complained about those people that they usurped his rights and said that their repentance is not accepted and they suffer the chastisement of Allah in Barzakh (grave/or intervening period between death and resurrection), till they go to Hell. How similar is this example of Moosa with Qaem Aale Muhammad (a.s.) who was born in secrecy and was always fearful of the Firon and his followers and was hiding from them.
Till he appeared and overpowered them and Imam Qaem Aale Muhammad’s reappearance would also be like this. Insha Allah. In Maniul Akhbar there is a tradition from Mufazzal that Imam Sadiq (a.s.) said: One day the Holy Prophet (S) saw Ali and Imam Hasan and Husain (a.s.) and started weeping and said that after me you would be made weak. Mufazzal asked: What did the Prophet meant by it?
