The Conflict of the Ma'mums' Tasbih Regarding the Imam

Question : If one man recites tasbih indicating that the imam added [to the prayer], and another man recites tasbih indicating that he did not add.

Answer : Huh? I mean, their testimonies cancel each other out; their testimonies cancel each other out. One of them said to him, "When he stood up, he said Subhan Allah," and when he prepared to sit, the second one said, "Subhan Allah." So when two statements conflict in his view, they cancel each other out; the two statements cancel each other, and each statement invalidates the other. He returns to what he has and builds upon it. And it will come, if Allah wills. In any case, the tasbih of two trustworthy people is necessary.
