Nutjobs like Tzortzis will say that the quran is not Saj even though many academics cited by klingschor agree it is saj.
Well that's all just playing with semantics - whatever you call it, these verses above are in exactly the same style as the Qur'an. They flow beautifully. There is nothing superfluous in them that's just for rhyme etc... they are full of meaning and are amusing and spot on. They are as good - and indeed much better than some verses of the Qur'an.
I had a go writing a few verses my self a while ago and these ones are better than mine, which were a little frivolous - these have more gravity and harmony and maintain there message throughout without any need for adding artifice or padding.
There is absolutely no doubt in my mind these 21 verses are as good as anything in the Qur'an.
