وَكَمْ قَصَمْنَا مِن قَرْيَةٍ كَانَتْ ظَالِمَةً وَأَنشَأْنَا بَعْدَهَا قَوْمًا آخَرِينَ فَلَمَّا أَحَسُّوا بَأْسَنَا إِذَا هُم مِّنْهَا يَرْكُضُونَ لَا تَرْكُضُوا وَارْجِعُوا إِلَى مَا أُتْرِفْتُمْ فِيهِ وَمَسَاكِنِكُمْ لَعَلَّكُمْ تُسْأَلُونَ قَالُوا يَا وَيْلَنَا إِنَّا كُنَّا ظَالِمِينَ فَمَا زَالَت تِّلْكَ دَعْوَاهُمْ حَتَّى جَعَلْنَاهُمْ حَصِيدًا خَامِدِينَ
“(The people of) how many towns there were iniquitous did We destroy, and We raised up after it another people! So when they felt Our (approaching) torment, lo! They began to flee from it. (We said:) ‘Flee not, but return to that wherein you revelled, and your dwellings, haply you will be questioned. They said: ‘Woe to us! Verily, we were unjust! And this cry of theirs ceased not, till We made them like reaped corn, extinct”
Explaining the above verse, Imam Baqir (as) said, When the Qaem (as) rises, he will send (his army) to Shaam to the Bani Umayyah, but the Bani Umayyah will run toward the Romans.
However, the Romans will say to them, “We will not give you refuge unless you become Christians.”
Therefore, the Bani Umayyah will wear crosses around their necks and the Romans will allow them to enter (their cities.) When the companions of the Qaem (as) reach the Romans, they (the Romans) will ask for safety and asylum.
However, the companions of the Qaem (as) will say to them, “We will not grant asylum to you unless you surrender those who sought refuge with you from us.”
So the Romans will surrender the Bani Umayyah to the companions of the Qaem (as).
(The companions of the Qaem (as) will say to the Bani Umayyah), “Flee not, but return to that wherein you revelled, and your dwellings, haply you will be questioned” . The companions of the Qaem (as) will ask the Bani Umayyah about the whereabouts of their treasures, despite being more knowledgeable about it.
That is when the Bani Umayyah will say, “Woe to us! Verily, we were unjust!” .
Imam Baqir (as) continued, “And this cry of theirs ceased not, till We made them like reaped corn, extinct” by sword. (Al Kafi volume 8 page 51)
Regarding the words of Allah – “So when they felt Our (approaching) torment, lo! They began to flee from it”, Imam Baqir said, The “(approaching) torment” refers to the rising of the Qaem (as) (Taweel Al Ayat Al Zahirah page 320)
Imam Sadiq (as) explained the above verses by saying: “So when they felt Our (approaching) torment” refers to the rising of the Qaem (as).
“They began to flee from it” refers to the treasures that they (the Bani Umayyah) used to store.
“They said: ‘Woe to us! Verily, we were unjust! And this cry of their ceased not, till We made them like reaped corn, extinct” means that not even one of them will survive.
Imam Baqir (as) said (in a longer Hadith), It is as if I can see a little over three hundred and ten men rising from Najaf with their hearts as strong as pieces of Iron. Jibraeel will be to the right of the Qaem (as) and Mikaeel will be to his left. His fear will enter the heart of the people one month before he reaches them, and it will remain in their hearts one month after he leaves them. Allah will support him with five thousand high-ranked angels.
When he arrives in Najaf, he will order his companions to spend that night in worship. They will spend their night in Ruku’ and Sujood, praying until morning, at which point the Qaem (as) will order them to leave for Nukhaila. (This will all be happening) while Kufa is preparing an army against them.
(The Qaem (as) will reach the mosque of Ibrahim (as) in Nukhaila. After he performs two units of prayer, the army of Kufa, who will be from among the supporters of Sufyani and the Murji’ah, will rise against him.
The Qaem (as) will order his companions to relocate, and then he will order them to attack the army of Kufa. I swear to Allah that not even one of them will survive.
Then the Qaem (as) will enter Kufa, and every believer will proceed to Kufa. Ameerul Momeneen (as) said, The Qaem (as) will order his companions to move toward the oppressor, Sufyani. He will invite Sufyani to the Book of Allah and the traditions of the Prophet (sawa), so Sufyani will pay allegiance to him.
However, the Bani Kalb – who are the uncles of Sufyani – will say to (Sufyani), What did you do?! We will never pay allegiance to you.
He will ask them, What should I do?
They will tell him to fight desperately against the Qaem (as). (Sufyani) will prepare an army to fight the Qaem (as).
(However,) the Qaem (as) will say, Be careful! You have (already) paid allegiance, and (if you break it) I will fight you.
They will fight the next morning and the Qaem (as) will achieve victory. He will take Sufyani as a captive and then kill him with his own hands.
Then the Qaem (as) will send an army to the Romans to capture the rest of the Bani Umayyah. However, the Romans will refuse to surrender them, at which point the companions of the Qaem (as) will threaten to kill them. They will go back to their King and inform him.
(The Roman King will say), Give them the people they are looking for because they have come with great powers.
And Allah says, “So when they felt our approaching torment, lo! They began to flee from it. (We said): Flee not, but return to that wherein you revelled, and your dwellings, haply you will be questioned” about the treasures that (the Bani Umayyah) used to keep.
“They said, ‘Woe to us! Verily, we were unjust! And this cry of theirs ceased not, till We made them like reaped corn, extinct”. Therefore, not even one from among them will survive. (Tafseer Ayyashi volume 2 page 56)
