Then We gave you back the turn to prevail over them, meaning, We gave the Umayyads back the turn to prevail over Aale Muhammad (a.s.) and We succored you through wealth and progeny and We made your band of greater number compared to Husain Ibne Ali (a.s.) and his companions, when the womenfolk of Aale Muhammad (a.s.) were taken hostage. If you should do good, you do good for your own selves and if you should do evil, you do it against yourselves.
So when the second promise comes to pass, meaning the Qaim (a.s.) and his companions, so they may make discountenance you, meaning rendering their countenances dark, and so they may enter the Mosque as they entered the first time, meaning, the Messenger of Allah and his companions, and to destroy utterly that which they ascended to, that is, they will prevail over you and will kill you.
Then the verse shifts to Aale Muhammad (a.s.) and says: Perchance your Lord will have mercy on you, that is, He will grant you victory over your enemy. Then it addresses the Umayyads, If you again return, We will return, that is, If you return with Sufyani, We will return with the Qaim from Aale Muhammad (a.s.). 4- أَوْ يُحْدِثُ لَهُمْ ذِكْرًا “…or that it may produce a reminder for them.” (Surah Taha 20:113)” … that is, remembrance of the reappearance of the Qaim and advent of the Sufyani.
