If you are in doubt of what We have revealed to Our votary, then bring a Surah like this, and call any witness, apart from God, you like, if you are truthful.
Na ikiwa mna shaka kwa hayo tuliyo mteremshia mja wetu basi leteni sura moja ya mfano wake, na muwaite mashahidi wenu badala ya Mwenyezi Mungu, ikiwa mnasema kweli.
