42 How do we know that there is revelation, and that it is from Allah? Here is a concrete test. The Teacher of Allah's Truth has placed before you many Surahs. Can you produce one like it? If there is any one besides Allah, who can inspire spiritual truth in such noble language, produce your evidence. Or is it that your doubts are merely argumentative, refractory, against your own inner light, or conscience? All true revelation is itself a miracle, and stands on its own merits. (Cf.
10:38;
11:13 ).
