Tradition

It is narrated from Abu Baseer that he said: I asked Imam Sadiq (a.s.) regarding the interpretation of the verse: “He it is Who sent His Apostle with guidance and the religion of truth, that He might cause it to prevail over all religions, though the polytheists may be averse.” (Surah Taubah (9):33)
He said – By Allah, its realization has not come yet. I asked – May I be your ransom, when will it be realized? He said – When the Qaim rises, God willing. When the Qaim rises, there will be no disbeliever or a polytheist but he will dislike his rise. Even if there will be a disbeliever or a polytheist under a rock,
the rock will call out – O believer, there is a disbeliever or a polytheist under me, so kill him.
So Allah brings the disbeliever to him, and he kills him.
