And if you (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Quran) to Our slave (Muhammad Peace be upon him), then produce a Surah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allah, 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.
