Please calm down. I have the honor of translating the Qur'an, so let me humbly state that the term "Ayah Kareemah" applied to a part of Ayah 21:87 is a human endeavor. Every verse of the Qur'an is Kareem (Honorable). Allah did not name 21:87 as "Ayah Kareemah".
If we keep repeating that part of 21:87 "LA ILAHA ILLA ANTA SUBHANAKA INI KUNTU MIN AZ-ZAALIMEEN" millions of times, it won't benefit us, but waste our precious time. Did Allah command us to do that?
2:231 … Do not make Allah’s verses a laughing stock …
