Shaving ear hair is generally considered permissible in Islam.
Based on Islamic teachings, the religious texts specifically detail which types of body hair should be removed or are forbidden to be removed. However, ear hair is not explicitly mentioned in these texts. This silence implies that the default principle (i.e., the basic principle of Sharia) applies, which states that actions not explicitly forbidden are permissible. Therefore, removing ear hair falls under this category of permissible actions.
In essence, because there is no specific Islamic prohibition against shaving ear hair, it is considered Halal (permissible).
