However, a practical proof of this claim was that despite being pressed by an enemy of Islam Mirza could not perform even a single miracle. It is obvious that had there been an iota of truth in his claims of having been appointed by God or that he has power of performing miracles or that God has promised him that a heavenly sign will be exhibited at his hands, then at such a critical juncture when an enemy of Islam was lampooning Islam and openly attacking the Holy Prophet of Islam SAAW, there was no reason why Allah would not have instantaneously shown a sign at the hands of his appointee.
Hata hivyo, ushahidi wa vitendo wa dai hili ulikuwa ni kwamba, licha ya kubanwa na aduwi wa Uislamu, bado Mirza hakuweza kufanya hata muujiza mmoja. Ni dhahiri kuwa kama kungelikuwa na chembe ya ukweli katika madai yake ya kuteuliwa na Mungu au madai ya kuwa na uwezo wa kufanya muujiza au madai ya kuwa Mungu amemuahidi kuwa ishara ya mbinguni itaoneshwa mikononi mwake, basi katika wakati huo mgumu ambapo aduwi wa Uislamu. Alikuwa akiuponda Uislamu na kumshambulia Mtume(s.a.w), hapakuwa na sababu kwanini Allah, pale pale asioneshe ishara mikononi mwa Mteule wake? Si hivyo tu kwamba hakuweza kuonesha muujiza wowote bali hakuweza hata kumpatiliza kwa laana aduwi huyu wa Uislamu kwa maneno yake. Aliwazuiya hata wengine kukabiliyana naye.
