Q 1:
Boxing is
a game in which two participants punch each other in the face. As a result, this might cause one of the boxers to lose consciousness. Moreover, the thighs of the players and their `Awrah (parts of the body that must be covered in public) are uncovered.
A:
Boxing is not permissible for the great danger it entails. Allah (Exalted be He) says:
...and do not throw yourselves into destruction
And:
And do not kill yourselves (nor kill one another). Surely, Allâh is Most Merciful to you.
The Prophet (peace be upon him) said:
There should be neither harming nor reciprocating harm
It is not permissible to uncover thighs and the rest of the `Awrah. (Part No. 15; Page No. 200) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
