«أَوِّلِ الْقَصِيدَةْ كُفْرْ»

The saying applies when a shocking or reprehensible matter displays its most objectionable feature at the very beginning. Rather than emerging gradually, the gravest offense is immediately visible and shapes the first impression.

It is a disapproving comment on an affair whose opening is already its most outrageous part. The point is not that later developments will be worse, but that the initial moment itself plainly reveals the extent of the problem.

Use it to criticize a situation, proposal, account, or performance whose most offensive feature appears at once. It is a pointed remark for cases in which the beginning immediately exposes what is most unacceptable about the matter.
