Does not Ibn Masoud's anger prove that "al-namṣ" (plucking/epilation) is not limited to eyebrows only? And does removing facial hair - by "al-namṣ" - constitute altering Allah's creation? If so, does this ruling apply to the rest of the body hair?

Scholars have differed on the definition of an-namṣ (plucking) that is forbidden in the ḥadīth. Some said it is plucking facial hair, while others said it is removing facial hair by any means. However, many scholars believe it refers exclusively to the eyebrows. This interpretation is supported by what At-Tabarī reported from Aisha (may Allah be pleased with her) regarding the removal of harm from the forehead. The argument that Aisha's ḥadīth predates the ḥadīth of cursing is incorrect, as it occurred after the Prophet's (peace be upon him) passing. As for Ibn Mas'ūd's ḥadīth, it does not mention thinning the forehead; rather, it clarifies that only those cursed by the Messenger of Allah (peace be upon him) are cursed, and Allah Almighty says: {And whatever the Messenger has given you—take it; and what he has forbidden you—refrain from it.} Finally, a woman's hair is divided into three categories in terms of its removal, and the forbidden namṣ specifically concerns the eyebrows.
