The rejecters of the Truth keep complaining, "Why has no miracle ever been bestowed upon him from his Lord?" You (O Prophet) are but a Warner for every nation there is and ever will be. (The Perfect Divine Guidance through the Prophet shall be preserved in the form of the Qur'an for all times and all peoples (6:34), (6:91), (6:116), (10:64), (15:9), (18:27), (41:53), (75:16-19). And his prime duty is to counsel mankind that false individual or collective systems of life only end up in disaster).
