What is the challenge of the Qur’an?
Well, traditionally – that is to say – qur’anically, the challenge was literary or perhaps one of orality, because the culture the Qur’an came into was a time where the poets were esteemed and would hold sparring verbal competitions like modern day spoken word slams and rap battles; spontaneity and immediacy was the order of the day.
However, putting the spontaneity aside to make things easier for the challengers, the Qur’an itself says, a number of times with slight differences of emphases each time, the following:
Ten Surah Challenge: ‘Or do they say, “He invented it”? Say, “Then bring ten surahs like it that have been invented and call upon [for assistance] whomever you can besides Allah, if you should be truthful.”‘ (Qur’an 11:13)
