When you had announced your miracle, you should have full belief that you will definitely perform the miracle and its impact would be right on the mark and he who witness it would surely embrace Islam. The literal meaning of miracle is to make everyone powerless.
Wakati ulipokuwa umetangaza muujiza wako, ungelikuwa na imani thabiti kwamba pasiposhaka utaufanya muujiza huo na athari zake zingetokea pao hapo na yeyote ambaye angeshuhudiya basi kwa hakika angeukubali Uislamu. Maana ya Kiistilahi ya muujiza ni kumfanya kila mtu aondokewe na uwezo.
