A:
it is not permissible to lighten above and below the eyebrows in the way that was mentioned, as it entails changing Allah's creation and resembles Nams which is prohibited, (Part No. 24; Page No. 104) being in the same sense. It is even more prohibited if it entails imitation of non-Muslims, or if it is harmful to the body or hair. This is because Allah (Exalted be He) says:
...and do not throw yourselves into destruction
The Prophet (peace be upon him) also said:
"There should be neither harming nor reciprocating harm."
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
