The Dalá’il-i-Sab‘ih (Seven Proofs), the most important of the polemical works of the Báb, was revealed during that same period.[Máh-Kú] Remarkably lucid, admirable in its precision, original in conception, unanswerable in its argument, this work, apart from the many and divers proofs of His mission which it adduces, is noteworthy for the blame it assigns to the “seven powerful sovereigns ruling the world” in His day, as well as for the manner in which it stresses the responsibilities, and censures the conduct, of the Christian divines of a former age who, had they recognized the truth of Muhammad’s mission, He contends, would have been followed by the mass of their co-religionists.
